Notary bounce format has been added to 1.8c a long time ago. The problem
with unix is sendmail, for a change :-) If the new feature is popular
enough, I expect that sendmail will be modified to work with it, and if
nobody likes it, it won't matter. Besides, only 1 LISTSERV list in 5 runs
under sendmail, so it isn't as bad as it sounds.
