I just tested a rule with the three regexps
^subject:.*Accepted.*
^subject:.*Declined.*
^subject:.*is out of office.*
copied from your post and Action set to Reject, and a message with
Subject: [Somelist] Declined: Invitation to workshop on 13rd Dec. 2008
was rejected for matching the rule. Perhaps you didn't set the rule
action. Note that Action = Defer does not mean defer the post; it
means defer the rule - i.e. don't enforce it.
