Release Notes: Fedora 10 is supported. tnef was upgraded to 1.4.5. A patch was added to ClamAV and SpamAssassin to make the Mail::ClamAV Perl module handle ClamAV 0.94 correctly. mcafee-autoupdate was fixed so that it will work properly.
Release Notes: There is now an alternative phishing net which is less strict than the original. It knows all about top-level and second-level domain names in countries around the world, and will allow a link that points to the same company as the text it claims to be. This is particularly useful for ISPs who cannot use the phishing net because it caused too many false alarms. Support for Sophos 5 has been added. Contents of gzip-ed archives will now be checked for filenames and filetypes. Detection and removal of Web bugs was improved.
Release Notes: A "Use TNEF Contents" feature was added, which you can use to add to a message the attachments which are held in the "winmail.dat" file in an "Outlook Rich Text Format" message.
Release Notes: There are great speed improvements, often as much as a 40% speed improvement. Virus scanners are automatically detected. No configuration is required on sendmail systems. A UU-decoder was added to allow filename and filetype traps in UU-encoded files inside attachments. Many command-line options were added to the "MailScanner" command so you can test your configuration, evaluate rulesets, and debug your installation without have to set the debug options in MailScanner.conf.
Release Notes: This version is noticeably faster than before. File name and file type restriction rules are also greatly simplified, so everyone can actually understand it.
Release Notes: The major new feature is a rearrangement of how the spam.assassin.prefs.conf is used. This is now linked into the site-rules directory of SpamAssassin, so it is automatically read by SpamAssassin's startup code, and no special file reading code is included in MailScanner any more. The installation scripts should take care of all of this for you. There is also a new feature to reject selected messages with a more polite report than the 1-line error message generated by your MTA when it rejects a message.
Release Notes: This version now detects and blocks password-protected zip files, and can apply filename and content checking to the files archived in zip files. This is in addition to the virus scanning of the contents of zip files which has been provided in the past.
Release Notes: The MIME decoder is now much more robust and better at finding hidden or broken attachments. A list of viruses known not to forge their "From" address, such as macro viruses, was included, so you can warn the senders. The envelope sender and recipient addresses can now be added to the headers of the mail message, easing the administration of black and white lists. There were also many other changes and improvements.
Release Notes: The ability to "disarm" dangerous HTML tags while leaving the bulk of the message intact, a means to throttle SMTP connections from "spam zombies" and virus-infected systems as protection against a Distributed Denial of Servce (DDoS) attack, and the ability to set the ownership and permissions on the quaratine to ease web management without the need for risky setuid scripts have been added.
Release Notes: The major new features are filetype detection regardless of filename used, control over HTML forms in email to protect against credit card theft, and control over the size of each message. All these are configurable per user, like everything else, so you can set different thresholds and rules for different classes of user.
