I haven't edited my .procmailrc or any of its includes for at least a
week. Yet Saturday night (27 hours after I left this office Friday)
procmail started sending me a duplicate (from foo(_at_)bar) of every incoming
message on a particular mailing list. Worse yet, the log for one of those
messages says that the recipe for that list is an "invalid regexp"
Impossible, I say--the message is a duplicate of one that was successfully
routed to the list folder!
I don't want to dump a flood of diagnostic data on this list. Any glutton
for punishment who wants to take a look at it, let me know what I should
send you.
