Howdy, I know this subject has been visited before but.... Has anyone come up with any heuristics that procmail can use to determine that a message to a mailing list from a poorly configured autoresponder (the message appears to come from an individual and does not include headers from daemons, proper Precendence: , etc) and prevent it from creating an infinite loop with the mailing list? I realize people who can't properly setup an autoresponder have no business using one and should be publicly humiliated at their local soccer stadium, however this is not an option available to me.
