FROM_MAILER and FROM_DAEMON match too much

I'm having trouble with a user whose email address is
user(_at_)mail(_dot_)company(_dot_)com(_dot_)  Apparently, the "mail" part 
after the "@" is
causing the FROM_DAEMON and FROM_MAILER regexps to match.

Does anyone have an easy fix for this?

I'm running procmail v3.11pre3.

Thanks,
== Bob
