After a recent upgrade to sarge, I decided to update exim to exim4. This was
fairly painless, until I tried to configure spamassassin.
Following instructions at: http://koivi.com/exim4-config/
I added a transport to /etc/exim4/conf.d/transport/30_exim4-config_spamcheck
and a router to /etc/exim4/conf.d/router/850_exim4-config_spamcheck_router
Mail is still being delivered fine, but the SPAM headers are not being added
to the received email and the /var/log/exim4/mainlog reports that mail is
being collected and delivered immediately to the necessary Maildir folder.
What am I missing? How do I get Spamassassin to scan the mail and tag it so
that I can filter it out with .forward rules, as I had previously? I
upgraded in the hope I could get sa-learn working, but so far spamassassin is
a non-starter.
Any help would be appreciated.
