I get mails not recognized as spam and I would like to extend
spamassassin to reject these mails. The mails look very normal, but the
message-id is conspicuous. I want to reject the mail if it contains
.local at the end of message-id.

My system is debian, amavis, spamassassin, clamav. How can I extend
Spamassassin? Or can I just call /usr/bin/sa-update --no-gpg regularly
and wait to get better ruleset?
