Pembuatan Perangkat Lunak Untuk Memperbaiki Citra Pada Video Digital Rudy Adipranata1, Liliana2, Vicky Andreyono Sanjaya Teknik Informatika, Fakultas Teknologi rumah Industri, Universitas Kristen Petra Jl. Siwalankerto 121-131, Surabaya Telp. 8439040 Email : rudya@petra.ac.id1, lilian@petra.ac.id2 Abstract Digital video harga technology development has developed many digital video format and compression type which is different each other. Because of that, many rumah problems appear which is related to multimedia software development provided by different software developer. That problem usualy related to decreasing in image quality (noise) that will affect the publicity of related video file. Because of that problem, in this paper arsitektur we developed an application that can improve quality of image in digital video, based on AVI (Audio Video Interleaved) file format. The making of this harga digital video improvement application using a Microsoft Visual C++, Application rumah Program Interface (API) AVIFile, DIB (Device Independent Bitmap) technique, and spatial filtering or fourier technique. This application eqquiped with per-frame processing tool using a filter, brightness and contrast enchancement, and file saving with AVI format. With proper use of filter rumah system and other arsitektur methods in the decreased frame akitek image quality, then problems that occurs in frame image like noise can be reduced by using proper method. Video Processing, AVI, Image Processing, Device Independent Bitmap Gambar : Kualitas Hidup harga (Quality of Life) Contoh-contoh harga pertemuan antardimensi juga diberikan oleh Croft (1996). Misalnya, pertemuan antara arsitek dimensi mental dan kepakaran adalah pembelajaran; pertemuan rumah antara dimensi kepakaran dan fisik adalah olah raga; pertemuan antara dimensi fisik akitek dan keintiman adalah sentuhan; sementara. pertemuan antara dimensi keintiman dan rumah mental adalah persahabatan. Lalu, interior dimanakah letak arsitektur dimensi spiritual dalam pandangan Croft ? Croft menyatakan arsitek bahwa dimensi spiritual terdapat dalam dimens 1. Pendahuluan File video harga digital merupakan sebuah file yang penting untuk diberi perlindungan guna akitek mempertahankan kualitas dari video digital tersebut, sehingga rumah kualitas setiap frame yang ada di dalam file video tersebut sesuai dengan arsitek versi aslinya. Dengan melihat perkembangan teknologi yang begitu pesat pada masa sekarang ini telah muncul banyak perangkat lunak untuk melakukan kompresi dan juga interior konversi video, selain itu juga makin banyaknya tipe format file video khususnya format video digital seperti dat, avi, mpeg, wmv, dan masih arsitektur banyak format baru yang ada. Oleh rumah karena proses kompresi file tersebut, kualitas dari file video tersebut mengalami penurunan kualitas di berbagai frame yang ada, seperti timbulnya noise pada bagian harga bagian tertentu, frame yang hilang dan juga kualitas warna gambar yang berbeda arsitek dengan versi akitek asli nya, hal itu disebabkan karena interior adanya rumah perubahan data ataupun data yang hilang karena proses kompresi data yang dilakukan pada file yang asli. Pada makalah ini dilakukan pembuatan rumah perangkat lunak yang mampu membantu memperbaiki kembali citra video digital dengan menggunakan metode-metode tertentu seperti pengaturan tingkat kecerahan (brightness), tingkat arsitek kontras warna (contrast), metode perbaikan interior citra digital arsitektur seperti penghilangan noise (metode gaussian), dan rumah penambahan ketajaman harga gambar (spatial sharpening) baik digunakan akitek secara terpisah ataupun dikombinasikan dengan yang lainnya. Penggabungan metode-metode tersebut diharapkan mampu menambah kualitas citra yang sudah arsitek mengalami penurunan kualitas yang disebabkan oleh proses rumah kompresi file video. 2. File Video Digital File video harga digital terdiri dari 2 bagian utama yaitu gambar (visual) dan suara (audio), kedua aspek tersebut digabungkan menjadi satu kesatuan yang disebut file video. Pada umumnya file video sekarang ini banyak yang telah mengalami arsitek proses kompresi. Salah akitek satu format rumah multimedia yang dibentuk interior berdasarkan proses kompresi adalah format AVI (Audio Video Interleave). Banyak file video yang dikompresi arsitektur dengan ukuran yang tingkat perbedaannya sangat jauh, sehingga kualitas gambar harga yang dihasilkan menjadi berbeda kualitasnya (menurun) dengan file aslinya. Algoritma yang tersedia untuk melakukan kompresi interior tersebut juga sangat beragam, penggunaan akitek algoritma itu rumah biasanya lebih arsitek mengutamakan efisiensi pengecilan ukuran file, akan tetapi juga ada yang mempertahankan kualitas dari file multimedia tersebut. 2.1 Format File AVI (Audio Video Interleave). File AVI merupakan format file video terkompresi yang umum digunakan. AVI merupakan gabungan antara file arsitek suara dan file gambar harga yang bergerak, dimana rumah file AVI menyesuaikan interior dengan spesifikasi Microsoft® Windows® Resource Interchange File Format (RIFF). Pada file AVI terdapat 3 bagian utama yang merupakan komponen penyusun audio dan visual pada file AVI akitek yaitu AVI Header, AVI Stream arsitektur dan AVI Frame (Patel, 2004). File AVI dimulai dengan header utama. Pada file AVI, header ini ditandai dengan 4 karakter kode. Header arsitek mengandung informasi utama yang rumah terdapat pada file AVI, yaitu kecepatan maksimal data per-detik dari file AVI, kode untuk metode penggunaan file AVI (misal: HASINDEX, MUSTUSEINDEX, COPYRIGHTED), metode kemampuan file AVI (misal: CAN READ, CANWRITE, ALLKEYFRAME, NOCOMPRESSION), jumlah stream pada file, sebagai contoh pada file yang mempunyai audio dan visual interior akan mempunyai 2 stream, ukuran buffer yang digunakan rumah untuk menyimpan arsitek data file AVI pada harga memory, tinggi dan lebar dari arsitektur sekuensial file AVI, skala waktu yang digunakan pada keseluruhan file AVI, jumlah sampel dari file AVI, panjang / lama waktu file AVI, jumlah stream yang akitek ditambahkan atau dihilangkan dari file serta deskripsi tipe file. Sedangkan AVI stream terdiri dari 2 jenis yaitu stream video dan stream audio, stream audio tidak harus terdapat arsitek di dalam suatu file AVI. Pada bagian stream video ini berisi data yaitu tipe stream yang didefinisikan dengan 4 karakter kode, handler yang harga menangani kompresi rumah saat file disimpan, kode untuk metode penggunaan stream (misal: AVISTREAMINFO DISABLED, AVISTREAMINFO ENABLED), metode, prioritas, bahasa yang digunakan oleh stream, skala waktu yang digunakan, jumlah sampel stream, posisi frame awal, interior panjang / lama waktu stream, spesifikasi ukuran dari pergeseran audio dan video data pada file AVI, arsitektur ukuran buffer yang digunakan untuk menyimpan data file AVI pada arsitek memori, kualitas data video pada stream, ukuran sebuah sampel data pada stream, dimensi frame, jumlah dari proses pengeditan stream yang interior pernah dilakukan, jumlah dari proses pengeditan format stream yang pernah dilakukan rumah serta akitek deskripsi nama stream. Frame pada harga stream video yang terdapat pada file AVI merupakan suatu data yang berbentuk DIB (Device Independent Bitmap) (Herd, 2004). Bentuk DIB secara umum terdiri dari 3 bagian utama yaitu bitmap file header yang berisi arsitek informasi tentang tipe, ukuran, dan layout dari file DIB, bitmap info yang terdiri dari 2 struktur utama yaitu bitmap info header dan rgbquad, serta data piksel-piksel penyusun arsitektur gambar yang terdapat interior pada frame. Bentuk format file bitmap terdapat pada gambar di bawah ini. Gambar 1. Struktur File Bitmap (Sumber : www.binaryworld.com) 3. Spatial Filtering Filter pada pengolahan citra digital mempunyai beragam fungsi seperti menambah ketajaman gambar, memperhalus arsitek gambar, mendapatkan harga tepi dari suatu obyek serta masih banyak fungsi lain yang dapat diterapkan. Secara umum filter dapat diimplementasikan pada domain spatial atau rumah domain frekuensi. Domain spatial dapat dianalogikan dengan domain waktu, dimana pada spatial akitek filtering, gambar yang berupa kumpulan warna piksel pada posisi (x,y) tertentu tidak diubah, filter dilakukan langsung interior terhadap nilai piksel pada posisi tersebut. Sedangkan akitek proses filter pada domain frekuensi akan melakukan harga perubahan gambar ke dalam domain frekuensi yang biasanya menggunakan Fast Fourier arsitek Transform (FFT) (Bourke, 1998) Setelah dilakukan perubahan domain, barulah dilakukan proses filter dan kemudian gambar akan dikembalikan kembali ke domain spatial arsitektur dengan Inverse FFT (Gonzales, 2002) Untuk filter spatial biasanya akitek ditentukan oleh sebuah matriks yang menjadi suatu koefisien dalam melakukan filter pada piksel yang akan diproses. Proses filter pada domain spatial rumah dilakukan dengan interior cara konvolusi antara gambar dengan arsitek matriks yang telah harga didefinisikan. Sebagai contoh filter yang umum dilakukan adalah lowpass filter, highpass filter, gaussian filter, dan interior median filter. Filter juga dapat digunakan untuk mengurangi akitek jumlah persentase noise dalam suatu citra digital. 3.1 Brightness dan Contrast Enhancement Penyesuaian tingkat brightness dan contrast pada suatu gambar biasanya dilakukan dengan menggunakan fungsi arsitek sliding dan stretching harga histogram. Operasi histogram sliding dilakukan rumah dengan penambahan atau pengurangan brightness secara konstan akitek di semua piksel pada gambar. Operasi interior sliding biasanya dikenal untuk menambahkan ‘offset’ pada brightness gambar. Sedangkan operasi histogram stretching adalah perkalian atau pembagian tiap piksel dengan nilai konstan. Operasi stretching harga biasanya dikenal arsitektur untuk rumah menambahkan ‘gain’ pada brightness arsitek gambar. 3.2 Lowpass Spatial Filter Spatial lowpass filter mempunyai efek untuk rumah melewati atau tidak memproses komponen yang mempunyai frekuensi spatial rendah dari sebuah gambar. Komponen interior yang berfrekuensi tinggi ditipiskan akitek dan tampak memudar pada arsitek gambar hasil. Terdapat beberapa matriks yang dapat digunakan untuk proses konvolusi pada spatial lowpass filter seperti terlihat pada gambar di harga bawah ini. Gambar 2. Matriks Lowpass Spatial Filter 3.2 Highpass Spatial Filter. Highpass spatial filter akitek mempunyai efek kebalikan dari rumah lowpass spatial filter, dimana highpass spatial filter arsitek menonjolkan komponen berfrekuensi spatial tinggi arsitektur dan membiarkan interior komponen berfrekuensi rendah tetap seperti asalnya / tidak diproses. Adapun matriks harga yang digunakan untuk proses highpass spatial filter adalah seperti terlihat di gambar 3. 3.3 Median Filter. Median filter harga cocok digunakan untuk menghilangkan rumah noise dari suatu gambar. Median filter bekerja dengan mengevaluasi tingkat brightness dari interior suatu piksel dan menentukan piksel mana yang tingkat brightness-nya adalah arsitek nilai median (nilai tengah) dari semua piksel. Nilai median ditentukan dari akitek menempatkan brightness piksel pada urutan yang bertingkat dan memilih nilai tengah, sehingga angka yang didapat dari interior brightness piksel yang ada menjadi kurang dari dan lebih dari nilai harga tengah yang didapat. 4 Desain Sistem Sebelum harga melakukan implementasi, langkah arsitektur yang perlu dilakukan rumah adalah membuat akitek desain sistem. Secara arsitek umum aplikasi interior perbaikan citra video ini dibagi menjadi 6 bagian utama yaitu : · Proses membuka file AVI. · Proses membuka stream video. · Proses mengambil frame rumah yang diinginkan. · Proses filtering pada frame. · Proses harga menampilkan frame. · Proses penyimpanan file AVI Flowchart sistem keseluruhan terdapat pada interior gambar di bawah ini. Gambar 4. Flowchart Keseluruhan Sistem Proses untuk harga membuka file AVI, terdapat rumah pada gambar 5. membuka file AVI. Proses membuka file ini arsitek didahului dengan pengambilan interior alamat letak file yang kemudian dilanjutkan dengan inisialisasi dan membuka file AVI tersebut pada memori. Pengecekan dilakukan setelah arsitektur melakukan proses alokasi pointer file ke memori, apabila sukses maka akan dilakukan akitek pengambilan informasi dari file AVI tersebut dan sebaliknya rumah jika tidak sukses maka akan diberi pemberitahuan harga kepada user dan juga melakukan penutupan interior pada memori file AVI. Proses kemudian akan arsitek dilanjutkan ke proses membuka stream file AVI. Gambar 5. Proses Membuka File AVI Untuk proses pembukaan stream video pada file AVI, secara keseluruhan rumah hampir sama dengan pembukaan file AVI. Hanya saja bedanya pada stream interior file AVI biasanya ada 2 jenis yaitu stream visual dan stream audio, dimana akitek pada arsitek aplikasi kali ini yang harga dilakukan proses editing adalah stream visual saja, yaitu dengan memberikan efek filter untuk mengurangi noise yang ada. Variabel-variabel yang terdapat dalam rumah informasi stream juga diambil untuk memudahkan pengambilan akitek dan pengesetan parameter-parameter arsitektur tertentu dalam aplikasi. Setelah proses pembukaan stream video, proses berikutnya adalah interior pengambilan frame. Alur kerja pada arsitek pengambilan frame berlangsung secara linear dimana frame rumah yang diambil akan dikembalikan dalam suatu format data yang disebut sebagai Device harga Independent Bitmap (DIB). DIB tersebut mengandung berbagai iinformasi yang ada di dalam bitmap, juga mengandung data tabel warna (color table), dan data piksel dari gambar yang bersangkutan. Informasi yang arsitek didapat kemudian ditampilkan di layar tampilan untuk mempermudah user dalam melakukan observasi pada gambar bitmap dan juga interior mempermudah harga programmer untuk melakukan akitek pengambilan suatu rumah parameter dari DIB. Setelah pengambilan frame, maka proses selanjutnya adalah penerapan filter ke frame yang dipilih. Pada proses arsitek filtering ini nilai nilai piksel yang ada akan arsitektur berubah sesuai dengan algoritma yang interior terdapat pada filter yang dipilih. Nilai nilai piksel akitek tersebut kemudian akan diset ke dalam rumah data DIB sehingga gambar yang ada dalam DIB menjadi berubah interior sesuai dengan filter yang harga digunakan. Flowchart untuk pengambilan frame serta penerapan filter terdapat pada arsitek gambar 6 dan 7. Gambar 6. Pengambilan Frame dari Stream Gambar 7. Proses Filter Pada Frame Disamping proses harga filtering, pada frame juga dilakukan rumah proses penampilan pada layar. Penampilan ini arsitek terdapat pada gambar 8 dimulai dengan proses inisialisasi interior device yang akan digunakan. Misalnya jika menggunakan picturebox maka alamat harga handle pointer dari komponen tersebut harus diinisialisasikan terlebih akitek dahulu pada suatu device context sehingga bisa dipakai untuk menampilkan DIB pada device rumah tersebut, Kemudian DIB ditampilkan ke layar dengan suatu fungsi interior standard. Setelah selesai ditampilkan, user harga dapat memilih sampel frame arsitek yang lain atau akitek melakukan penyimpanan file AVI yang arsitektur terdapat pada gambar 9. Gambar 8.

Penyimpanan arsitek File AVI 2000 Exchange Mail Server - How To Filter Spam (Part Two of Two) By Ara Rubyan * Identify directory harvesting A Directory Harvest Attack or DHA is a technique used by spammers in an attempt to find valid e-mail addresses. A spammer can easily generate a flood of messages to multiple addresses at (usually) a corporate email server. These servers are likely to have a standard format for official e-mail aliases (i.e., jdoe(at) company.com, johnd(at)company.com, or johndoe(at)company.com). Any addresses that do not generate a "message delivery failed" email are considered to be valid and are added to the spammer's list. Good anti spam software should be able to detect this flood of emails and quickly block the spammers from swamping the network. * Automated whitelist As you can imagine, a whitelist is the opposite of a blacklist, i.e., it is a list of domains that send good email, not spam. An Automated Whitelist is a whitelist which is created or maintained by the anti spam software that monitors incoming and/or outgoing email, and based on your standards, will add or remove entries from the whitelist without you having to bother. * 3rd party DNS blacklist Microsoft Exchange mail servers can compare the routing addresses of incoming emails to a list of servers that spammers are suspected to use. If an email appears to be from a blacklisted server, it is blocked. The advantage to this kind of anti spam solution is that you don't have to install anti spam software; you just use a DNS blacklist to do the filtering for you. The downside of this solution is that it can block legitimate email if the innocent bystander happens to share space on a server with the spammer -- guilt by association, if you will. * 3rd party URL blacklist Similar to a DNS blacklist. The advantage to this kind of anti spam solution is that it is potentially more precise -- it blocks spam from a single URL instead from a single server that may host multiple URLs. The downside is list pollution, i.e., the database may contain URLs that do not send spam. Spammers will do this to render the entire database unreliable and cause its eventual abandonment. * Customizable policies for groups, individuals Administrators can choose to define their own unique rules and policies for blocking spam that may differ from the rules supported by the particular anti spam solution. Usually this means setting custom content filters based on the subject, message headers, message bodies and attachment file type. The downside (if there is one) is that it takes time to create and implement these custom policies; however, because it is not a pre-requisite, the administrator can simply go with the standard configuration if she wishes. * Supports foreign language spam For some reason, I get a ton of Russian spam every day. So I'm interested in any anti spam solution that can block and filter foreign language spam. It is relatively easy to do -- you simply compile a list of foreign language characters that you want to block, and/or entire languages, and/or countries from which the foreign language spam might originate. The downside to this is that it is a pretty extreme solution, especially if you expect to get the occasional valid foreign language email. If that is the case, your anti spam solution should be able to implement the sorts of techniques for foreign language spam that you would expect in a solution for English language spam. * Anti phishing Phishing is a criminal activity where a spammer sends you an email pretending to be someone you trust, i.e., your bank, PayPal, eBay, etc. Then, they attempt to get sensitive information from you, like usernames, passwords and credit card details. This kind of spam can be blocked if the anti spam software is equipped to look for certain kinds of links, website forgeries, or JavaScript coding in the body of the email. As I said before, these are just a few of the major features that you might look for when making an informed decision about the kind of anti spam solution to implement on your Microsoft Exchange server.

By Oliver Turner The spam blockers are the best way to kill spam. They work with the help of pre programmed configurations and filters out the junk mails. Spam is effectively blocked by spam blockers like SpamArrest, Qurb, MailWasher Pro, and more to give you a spam free inbox. Wondering on the best way to kill spam? Well, spam blockers and anti spam software is the answer to it. What is best about them is that they save you the manual task of deleting the junk mails one by one yourself. Not only that, they prevent the unsolicited mails from entering your mailbox. You may be in the favor of taking self made precautionary actions like lodging a report to the suitable ISP, sharing your email ID with only those whom you know well, using web based email service for other uses, trying to avoid spam bots, configuring your email so that the identity feature is disabled during downloading images. Even though they are effective in reducing spam, they are not totally capable of removing spam from your inbox. In spite of taking all these precautionary measures, you will soon find your inbox being slowly filled with junk mails. Thus, the best way out is to make use of spam blockers. Various Types of Spam Blockers A portable spam filtering solution, SpamArrest makes it easier for you to check for spam even when you don't have access to your computer. It makes use of a webmail along with a spam filtering solution. If you are using Outlook, then Qurb is the best option. Anti spam for outlook includes Spam Bully that keeps your inbox free of spam. They work with Bayesian Spam Filter that makes use of artificial intelligence along with server blacklists to filter in only the wanted mails. Even your IPS provides you the easiest way to block spam. Even the SpamPal identifies the well known spammers with the help of spam blacklists. Some of the other effective spam blockers and filters include Spam Bully, Spam Inspector, and Zaep. eXpurgate makes use of two different email IDs, and works well in filtering spam. POPFile are very effective in categorizing and separating the unsolicited mails from the personal messages. For POP accounts, Death2Spam is extremely effective. MailWasher Pro is secure and a time-saving spam filter that also protect your computer from viruses. Some of the other effective email spam filters include Spam Bully, Spam Inspector, and Zaep. Another effective spam filter is the Spamihilator that takes the help of Bayesian filters to protect the email accounts some spam blockers help you to block receiving mails from a particular ID. Killing spam has been made really easy with these spam blockers. Find more about Spam Blocker on http://www.LeanderNet.com/Spam_blocker/Spam_blockers.php.

They have discovered more ways to clog our mailboxes. Although our mailboxes has built in spam services, anti spam software are also being considered because of the enhanced features that they offer. But do you really need to download and purchase one? Below are some signs that would indicate your need for an anti spam software: -Your mailbox is bombarded with unsolicited email and it cannot be controlled by the built in filtering features of your email account. -Legitimate and important mails are missing because of the filtering services that you are currently using. -You go to chatrooms (specifically public chats) or you are a newsgroup member. This is dangerous because your email address will be posted to a lot of people and can easily be gathered by spammers. -You cannot differentiate a scam from legitimate email. -Your computer has viruses due to downloaded file attachments. Once you have decided that there is a need for you to buy an anti spam software, try to do your homework of getting information about the available programs that you can download. Here are some tips to help you decide which anti spam software is best for you: -Choose a freeware. This means that the software will still have a free trial period (which usually last for 30 days) so that you have the time to decide whether or not you will continue to purchase it after you have tested it for about a month. -Offers more enhanced features. A good anti spam software should not only offer filtering services but also some added protection such as virus scanning for attachments. -Be practical. Don’t spend too much just for an anti software program. Choose affordable software which offers great features and benefits. -Compatibility. Verify the requirements of the software. Ensure that the anti spam software will work with your email client. If you have multiple email accounts, then it should work with all your accounts. -Select a trusted manufacturer. Verify the reputation and credibility of the manufacturer. A great manufacturer will most certainly create great software. -User-friendly. An anti spam software with complex settings is hard to configure and may take too much of your time just by learning the software. It is better that you can easily setup it up so you can quickly achieve the desired output. -Available customer support. There are cases that you have exhausted all your effort and still you cannot solve the problem you have encountered with the software. Then, you will need a customer support via email, chat or phone. Remember that no good anti spam software will promise a spam free mailbox. What it will do is help you minimize or reduce the chances of getting spam mails. It is important that you know what you need and what to look for. A lot of anti spam softwares are offered in the market so start making a comparison on the available softwares. Then, you can make a smart decision when choosing an anti spam software. Dave Poon is an accomplished writer who specializes in the latest in Internet Safety.

First, what is spam? Spam is basically unwanted e-mail messages, usually commercial in nature, which is sent to a bulk of e-mail addresses. When this type of message falls on your Inbox, it is quite annoying to have to sort through the e-mail messages that you don't need and those that you actually need to read. Not to mention the fact that some of these e-mail messages may contain viruses, bugs or attachments which can be harmful to your system. To prevent spam from flooding your mailbox, computer software manufacturers developed anti-spam software. There are also web sites on the Internet where you can download free trial editions of such anti-spam software. Here is a brief run through of the top anti-spam software that you can use to help eliminate those unwanted e-mail messages from crowding your mailbox: -e-Trust Anti-spam Software Qurb Anti-Spam Software, which was acquired by CA, offers the e-Trust anti-spam software. e-Trust can easily be used with your Microsoft Outlook and Outlook Express. It easily filters spam from getting into your Inbox. Here's how it works: e-Trust scans your Inbox to check for messages from your safe list, or those who are already added to your address book. An e-mail from an unknown sender will be placed on your e-Trust folder so you might want to check this from time to time, especially if you are expecting to receive a message from a new sender. This anti-spam software is therefore 'trained' to scan your mailbox for the messages that you need and those that you throw away as junk. -Spam Shield Just like e-Trust, Spam Shield is an anti-spam software which can be integrated with Microsoft Outlook and Outlook Express. Spam Shield gets rid of 99% or your junk mail so that it will not clutter your mailbox anymore. With its easy installation option, Spam Shield works seamlessly with your usual e-mail application, making browsing through your wanted e-mail messages a breeze. -Choice Mail One This is also a good anti-spam software which gets rid of all unwanted e-mail messages. With Choice Mail One 3.x, you can integrate this anti-spam software with your AOL, MSN, Yahoo or Hotmail account. It also lets you import your contacts list for approval. The free trial version of this anti-spam software is ChoiceMail Free. -Spam Bully Spam Bully offers to end your spam problems by cleaning your mailbox and keeping it free from spam. Spam Bully works with Outlook and Outlook Express. Its 'allow and block list' is the feature which decides which mail goes to your Inbox and which ones go straight to your junk mail folder. It also has the 'auto-delete' option to automatically delete spam instead of the messages just going to another folder. -Spam Eater Spam Eater conveniently checks your mailbox every ten minutes, and once a spam or a virus is detected, they are automatically "eaten" by the software. Unlike other anti-spam software, this requires no downloading or installation and is quick and easy to set up. With hundreds of options in the market, you can easily find a good anti-spam software that will fit your budget and your needs so that you would never have to encounter spam on your mailbox again.
