We have trained users to put misclassified ham and spam into two public
folders, should-be-spam and should-be-ham. We created an exchange user,
spamiam, that has full rights to these folders.
At the top of every hour, this script is run on the one MX server:
# more get_ham_spam
#! /bin/sh
rm -f /var/spool/mail/spamiam
touch /var/spool/mail/spamiam
chown spamiam:mail /var/spool/mail/spamiam
su spamiam -c 'fetchmail -a -K -f
/usr/local/scripts/spamiam.fetchmailrc -r "Public Folders/should-
be-spam"'
cat /var/spool/mail/spamiam >> /var/www/html/spamstuff/should-be-spam
sa-learn --spam --mbox /var/www/html/spamstuff/should-be-spam
rm -f /var/spool/mail/spamiam
touch /var/spool/mail/spamiam
chown spamiam:mail /var/spool/mail/spamiam
su spamiam -c 'fetchmail -a -K -f
/usr/local/scripts/spamiam.fetchmailrc -r "Public Folders/should-
be-ham"'
cat /var/spool/mail/spamiam >> /var/www/html/spamstuff/should-be-ham
sa-learn --ham --mbox /var/www/html/spamstuff/should-be-ham
# more spamiam.fetchmailrc
poll exchange.xxxx.com
proto imap
user spamiam
password xxxxxxxxx
is spamiam here
At 15 past each hour, the two other mail servers use wget to grab the
should-be files to their local /tmp and run sa-learn.
The files are included in logrotate, so they get zero'd every Sunday
morning.
