Actually, you might learn more by asking. The "automatic" method will
fail on at least one major piece of software... LISTSERV (tm). Therein,
in at least one mode, most envelope senders take on a default value.
However, as a list-owner option, and with list-owner specified
frequency, an occasional envelope goes out differently, with the
recipient's address encoded in it. This allows multiple mailings most
of the time, but with an ability to figure out what's bouncing
by sending individual mails from time to time.
Grabbing a sample envelope for a spam detector wouldn't get both
types, and even worse, might end up with the recipient bouncing
the probe message (which is the one that could be traced :-)
Cheers,
