I have a problem getting spamd and sendmail (both stock CentOS4 rpms) to work together on a couple of smtp relay machines. This is clearly a configuration issue and no doubt revolves around my lack of comprehension of how this is to work.
Basically, the setup consists of two frontend public smtp transports that redirect all email through a firewall to an internal imap server for final delivery. The firewall and sendmail access map prohibit connections to the imap server except for the local MX gateway. The external MX gateway is a fallback mx server that routes everything it queues through the primary gateway.
So:
MX 2 routes to MX 1 that routes to IMAP
MX 2 and MX 1 are running spamd.
the sendmail.m4 file has the following at its very end:
dnl # dnl # MAILERs are always last after all FEATURES are defined MAILER(smtp)dnl MAILER(procmail)dnl
The contents of /etc/procmailrc are:
:0fw | /usr/bin/spamassassin
Spamd is running on both.
There is a local configuration rule set in /etc/mail/spamassassin/local.cf
Passing a test message through spamc on MX 1 or MX 2 does not seem to pick up this rule even for messages constructed to trigger it. Passing spam messages through spamc -R identifies messages that have passed through the relays without any spam tags as being high scoring spam.
What am I doing wrong?

Procmail can only take action on locally delivered mail. I suggest using MailScanner for a complete, free & open solution. http://www.mailscanner.info http://wiki.mailscanner.info
Other people will probably recommend Amavis, but I've never used it.
