SpamAssassin is a mail filter which attempts to identify spam using a variety of mechanisms including text analysis, Bayesian filtering, DNS blocklists, and collaborative filtering databases.
Once identified, the mail can then be optionally tagged as spam for later filtering using the users own mail user-agent application.
SpamAssassin uses a wide range of heuristic tests on mail headers and body text to identify spam, also known as unsolicited commercial email.
SpamAssassin typically differentiates successfully between spam and non-spam in between 95% and 100% of cases, depending on what kind of mail you get and your training of its Bayesian filter.
Specifically, SpamAssassin has been shown to produce around 0.9% false negatives (spam that was missed) and around 0.1% false positives (ham incorrectly marked as spam). See the rules/STATISTICS*.txt files for more information.
Main features:
- Wide-spectrum: SpamAssassin uses a wide variety of local and network tests to identify spam signatures. This makes it harder for spammers to identify one aspect which they can craft their messages to work around.
- Free software: it is distributed under the same terms and conditions as other popular open-source software packages such as the Apache web server.
- Easy to extend: Anti-spam tests and configuration are stored in plain text, making it easy to configure and add new rules.
- Flexible: SpamAssassin encapsulates its logic in a well-designed, abstract API so it can be integrated anywhere in the email stream. The Mail::SpamAssassin classes can be used on a wide variety of email systems including procmail, sendmail, Postfix, qmail, and many others.
- Easy Configuration: SpamAssassin requires very little configuration; you do not need to continually update it with details of your mail accounts, mailing list memberships, etc. Once classified, site and user-specific policies can then be applied against spam. Policies can be applied on both mail servers and later using the users own mail user-agent application.

Outspring Mail 1.1.1 is an email program which can help you in various ways. Like offering to reply to certain types of email messages using a response you've previously sent. Or giving you the option to auto-file a message you've read based on how you've filed similar messages in the past. What if you could defer a message from your inbox for a few days or weeks, so that it magically reappears later when you're ready to deal with it? What if this program had an amazing junk mail filter that would leave your inbox devoid of spam? And what if this program was as familiar and easy to use as Apple Mail?

Outspring Mail is the newest email client for Macintosh.This tool can include the best features of existing email programs and coupled them with our patent-pending intelligent functions to create a program that will make your email chores far easier. And since this is a current-generation application, it supports major email protocols including POP, IMAP, SMTP and SSL. It also runs natively on the latest Macintosh computers and OS X Leopard. Demo notes: Launching the program and pressing the DEMO button (instead of entering a serial number) will place the program in demo mode, which is: All functions and features of the program will operate for 10 days. A "This message was sent with Outspring Mail..." tag will be added to all outgoing messages sent with the program. After the 10-day demo period has expired, the program will still work, but the user will not be able to send out mail or receive new mail until reactivated with a serial number provided at purchase.

Major Features:

1. Unique Features
   • Auto-Filing
   • Auto-Reply
   • Find Similar Messages
   • Reply with Template
   • Message Deferment
   • Message Preview with Intelligent Summary
   • Tabbed Display
   • Resize / Rotate Images
   • Mail Account Icons
2. Email With A Brain: Outspring Mail ushers in an entirely new category of software to the Macintosh: adaptive intelligent software. By using advanced database analysis and Bayesian logic, the program is able to ascertainImage patterns in the way you reply to and file your mail and make suggestions to assist you with your communications. Think about it...if you frequently reply to an email message that says, "How do I get to your office?" or words to that effect; shouldn't your email program be smart enough to know that you've replied to this same type of message before? And shouldn't it then offer to use one of these replies for the current message? The program also offers a similar technique for filing messages. Once the program has gone through a short learning process of observing your mail filing habits and cross-referencing message content, it will begin to suggest appropriate folders or mailboxes to file messages. Instead of dragging messages to folder icons, you'll be presented with one or more likely destination buttons that will automatically file your mail in an appropriate location.
3. Message Deferment: Another unique feature of Outspring Mail is a function called Message Deferment. This is much like the "snooze" button on an alarm clock. Many people will receive a message, read it, make a mental note to handle it later and then leave it in their Inbox. ImageAfter a few weeks or months, their Inbox becomes an unmanageable mess. But what if you could instead read the message, decide you don't want to deal with it this week and send it "away" for a week? The deferment feature then moves the message to a special folder and the program waits for the selected amount of time. When that time period has elapsed, Outspring Mail then moves the message back into the Inbox with an indicator reminding you that the message is a deferred message that has been returned.
4. Intelligent Summary:The product also contains a unique "Intelligent Summary" view. By using advanced summarizing algorithms, this feature allows you to quickly review email by a list of the summarized content, negating the need to open each message to see the heart of that content.
5. Spam Control:ImageOutspring Mail also contains an advanced spam filter that can eliminate 98% of your incoming junk mail. Having developed a server-side spam blocker for a number of years, Outspring has leveraged this experience into the spam filter which is included with the product.
6. Data Detectors For Calendar & Address Book: Another useful feature is data detection on incoming messages that link to the Macintosh built in Imagecalendar, iCal. If you receive a message that contains a phrase like, "Let's meet for lunch next Friday...", Outspring Mail will convert the phrase "next Friday" into a hot link. Clicking that link will take you to the iCal entry for the following Friday (based on the send date of the message). This Imagefeature works with literal dates like 1/15/09, May 15, 2008 and also with relative dates like "next Friday", "last Tuesday", etc.
7. Outspring Mail also links to your Apple address book, so contact data will be displayed within messages (like the contacts photo, if present). Clicking on that contact's image will take you to that entry in the address book.
8. Easy Transition From Apple Mail & QuickMailImage: Whether you are an existing Apple Mail or QuickMail user, you'll find it easy to import all of your existing email data into Outspring Mail. Our import assistant allows you to select which accounts you wish to import into Outspring Mail while leaving the database of the prior program intact. Import works with both POP and IMAP accounts.
9. ImageSpell Check Outspring Mail utilizes the the Macintosh system dictionary for spelling, corrections, synonyms and definitions. Misspelled words are highlighted as they are typed, which reduces the need to proof-read your outgoing messages. You can also check the definitions of words by simply control-clicking the word in question. By using the system dictionary, Outspring Mail is compatible with any language supported by OS X.

Enhancements: Bug fixes:

• Fixed a bug which prevented adding/removing columns in the message list.
• Fixed missing message headers when switching rapidly between messages.
• Fixed an issue with demo serial number invalid.

BOOMER is a general purpose modeling and simulation program. It provides the estimation of parameter values by non-linear weighted least squares regression or the simulation of complex systems of differential equations.
Parameter estimation can be by normal or Bayesian methods. A comprehensive list of weighting schemes is included. The model to be analyzed can be entered as a system of integrated equations or as a system of differential equations. Differential equations are solved by a classical fourth order Runge-Kutta method, a fourth order Runge-Kutta-Gill method, a four/five Runge-Kutta-Fehlberg method, an Adams predictor-corrector method, or Gears method for stiff equations. Simulation with random error in parameters or data are also possible. A batch run can be repeated many times to assist in Monte Carlo type studies.
Enhancements:
- Fixed a bug that caused a segmentation error with more than 30 adjustable parameters ;-)
- added form feed to output.

Quantum Fog can model physical situations that exhibit quantum mechanical behavior.

It is a tool for investigating and discussing quantum measurement problems graphically, in terms of network diagrams called quantum Bayesian nets. It simulates a general purpose quantum computer.

Intego Personal Antispam X5 10.5.3 is the intelligent spam-fighting tool for Mac OS X, which analyzes your incoming e-mail, determining which messages are spam and which are valid messages. Personal Antispam X5 learns from the e-mail users receive, and regular monthly updates to the program help keep inboxes as spam-free as possible.

In addition to keeping inboxes free of spam, Personal Antispam X5 helps protect against two serious threats: phishing and viruses. Some viruses circulate by e-mail as attachments, and Personal Antispam X5 detects specific types of attachments and moves messages containing them to the spam folder. As for phishing, e-mail scams intended to trick users into logging into web sites and giving up their passwords, account numbers or credit card numbers, Personal Antispam X5 detects and filters these messages in several ways: by the words they contain, the links in phishing messages, and specific types of layout.
