Postfix Virtual Mailboxes and Procmail Filtering

Am interested in getting procmail to work with my Postfix/Courier setup. Am using virtual domains/aliases/mailboxes stored in a MySQL database and a Maildir file system. Have only just begun my investigations. So far I’ve found:

SpamAssassin whitelist and blacklisting

Today I figured out how to specify whitelist and blacklist email addresses in SpamAssassin.

At the end of /etc/spamassassin/local.cf I added two lines:

include whitelist
include blacklist

Then in the /etc/spamassassin/whitelist file I added some email specifications, e.g.:

jj5@sixsigma:~$ cat /etc/spamassassin/whitelist
# Allow email from system services, e.g. from
# logwatch@hope.progclub.net or root@charity.progclub.org
whitelist_from *@*.progclub.*
# Similarly for blackbrick:
whitelist_from *@*.blackbrick.com

The /etc/spamassassin/blacklist file exists and is ready to go, but I haven’t blacklisted anything yet:

jj5@sixsigma:~$ cat /etc/spamassassin/blacklist
# No email addresses blacklisted yet.
#blacklist_from someone@example.com

Too easy.

There’s some more information on Whitelising a user.

At some point I hope to write a script that processes my users’ maildirs and whitelists everyone they’ve emailed.
