spamtrainer was written to assist mail services administrators in updating and maintaining their SpamAssassin bayes database. When run, it will read the designated HAM and SPAM mailboxes, update the SpamAssassin databases and delete mail that has been learned from. It furthermore has an array of additional functions. Among them the possibility to backup/restore your bayes database, fix the Tiger default installation and many more. This script is written for Mac OS X 10.4.x/10.5.x/10.6.x Server, but it will work on Mac OS X 10.3.x Server with SpamAssassin as well.
