FuzzyOCR is a plugin for SpamAssassin which is aimed at unsolicited bulk mail containing images as the main content carrier. Using different methods, it analyzes the content and properties of images to distinguish between normal mails (ham) and spam mails. FuzzyOCR tries to keep the system load low by scanning only mails that have not already been categorized as spam by SpamAssassin, thus avoiding unnecessary work. falko Thu, 29 Apr 2010 14:32:10 GMT http://www.howtoforge.com/groupware-server-with-group-office-postfix-dovecot-spamassassin-on-debian-lenny In this howto I will explain how you can set up a groupware server using the Debian Linux operating system, Group-Office for managing the mailboxes and groupware functions like e-mail, shared calendars, file sharing etc., Postfix with virtual accounts in MySQL, Dovecot IMAP, SpamAssassin spam filter, and a vacation perl script that will handle out-of-office replies. falko Thu, 26 Feb 2009 13:11:37 GMT http://www.howtoforge.com/block_spam_at_mta_level_postfix The last few weeks have seen a dramatic increase in spam (once again). Estimates say that spam makes now up for 80 - 90% of all emails, and many mail servers have difficulties in managing the additional load caused by the latest spam, and spam filters such as SpamAssassin do not recognize large parts of that spam as they did before. Fortunately, we can block a big amount of that spam at the MTA level, for example by using blacklists, running tests on the sender and recipient domains, etc. An additional benefit of doing this is that it lowers the load on the mail servers because the (resource-hungry) spamfilters have to look at less emails. falko Wed, 06 Jun 2007 09:59:29 GMT http://www.howtoforge.com/installing-maia-mailguard-on-debian-lenny This guide explains how to install Maia Mailguard, a spam and virus management system, on a Debian Lenny mailserver.

For example, it can be configured to deliver mails directly to a Maildir or mbox mailbox without the need for an MTA such as Postfix, but of course it can also pipe the mails through an MTA if you want. Getmail can use so called filters such as SpamAssassin and ClamAV to scan the mails, and you can even tell getmail to delete mails on the original server only after a certain number of days. falko Sun, 17 Jun 2007 10:34:45 GMT http://www.howtoforge.com/setting-up-a-mail-server-using-exim4-clamav-dovecot-spamassassin-and-many-more-on-debian This howto describes one way to build a scalable, secure, full-featured mail platform.
