The key here is contained in the last three lines of the maillog. I've recently seen this behavior on one of the servers I maintain and it happened just after upgrading a CentOS 4.3 server to 4.4. The problem is the Sendmail update.
I haven't updated sendmail since I made the switch to 4.4 in what...early September? It has been running happily since then. If I stop the spamassassin service, the mails come as expected.
Clearly choice number one is easier and much less painful since you won't have to switch out your configuration files for SA, ClamAV or Sendmail.
Thanks for the advice, and that's probably what I'll do, but I don't know why it just started last night.
