This is a procmail configuration problem: http://wiki.dovecot.org/MailboxFormat/Maildir#procmail Just wanted to say thanks for the help. You guys have made me a hero.
After reading the PostFix group and this group, and spending about a day sorting through a bunch of spam configuration stuff, I've got our mail server purring like a kitten. So I went to see the CTO this afternoon and explained the situation with the policy about RPMs. After him commenting that he had noticed a substantial drop in spam, his response was basically "You seem to have a clue; do whatever you think is appropriate."
Thanks again, guys.
Later, Chris
