Subject: getting rid of unwanted msgs?

You can control COMSAT messages by specifying the "R:" or "REGISTERED:" field
when sending mail from Babyl.  This is followed by one letter: A means COMSAT
will send receipts when mail is sent, queued or failed, F means send receipts
for failed mail only, N means return no receipts at all. By default, COMSAT
sends receipts for queued or failed mail (sort of in between A and F).

Note that this only applies to COMSAT (ITS mailer) receipts. You might still
get rejection or queued notices from other mailers.  Also it only works for
mail sent from ITS, since COMSAT will not parse foreign headers for this field.
