Hello all... I figure I've asked enough questions of this list that it's about time I gave something back... You may not want it,but here it is anyway :)
I've written a bash script that takes will run sa-learn against the administrator specified False-Postive and False-Negative folders. Run this script from cron, and have your users drag n' drop emails that get misclassified by SA to the appropriate folders. The script will act in 2 ways: 1.) Run it as root, and it will parse the administrator specified USERLIST and run the internally defined autoLearn() function as each user. 2.) Run it as an ordinary user and it will only learn from that user's email. I wrote it this way so that I could have a wrapper around sa-learn that would make sure that the directories exist, create them if they don't using maildirmake++, and not try to learn from directories with no messages in them. This is written to work with Courier IMAP and Maildir; I have not tried it with anything else. Someday I may get around to rewriting it in php and using php-imap to do the moving around etc, but as a dirty hack this works ok. It also doesn't need passwords etc. in config files... I hope this benefits someone out there... if there's enough interest, I'll put it on my website and do a proper CVS for it. If anyone has ideas for making it better (or suck less), let me know. Patches are always welcome... -- Rubin Bennett <[EMAIL PROTECTED]> RB Technologies

# Usage: IMAP users can move misclassified emails into the "False Negative"
# or "Flase Positive" folders, and this script will learn from them and put
# them where they belong.
# Spam will be moved to the designated Spam folder, and Ham will be moved to
# the user's Inbox.
# This script should be called by CRON or a similar scheduler.
# Requires:
# Maildir style email storage (i.e. Courier IMAP) and IMAP server
# Settings - tweak as necessary.
