Yes, but your problem is not well-enough specified yet.  What are you
trying to do here?  Prevent Joe Luser from posting "test" to see if
he's really subscribed or if the mailing list is down?  Or create a
"safety string" that the list admin can use to check if mailman is
receiving?  How much do false positives and negatives matter?
