iXhash is a plugin for the popular spam filter SpamAssassin. It computes MD5 checksums of fragments of the body of an e-mail and compares them to those of know spam using DNS queries to a RBL-like name server. In effect this gives SpamAssassin access to

Changes from 1.5.4. to 1.5.5 - Adam Stephens reported that hash #3 will be checked even though it has not been computed. This should be fixed now, saves a DNS query. Changes from 1.5.3. to 1.5.4 - Fixed some problems discovered by Bernd Holzinger and Larry Nedry, especially with hashing routine #3 not returning a return value. Larry noticed that as well as a discrepancy between the regular expression used by iXhash.pm and the hashcheck.pl tool Changes from 1.5.2 to 1.5.3 - Optimizations regarding the regular expression at hash #1 (entry condition). Thanks go out to Bernd Holzinger (regex Part 1) and Jan Schmidt. This should improve stability and performance quite a bit. Changes from 1.5.1 to 1.5.2 - Fixed a bug where a regexp testing the IP returned was wrong. It never matched - so no hits from iXhash. Gargl! Changes from 1.5 to 1.5.1 - Changed entry condition for hash #1. The one in 1.5 was borked. Also some lines were added to circumvent problems in Perl in some distros when using the originally intended regular expression (\s.+?){20} - Also added a declaration for $digest.
