I wasn't aware that Sendmail used a FILO queue for its recipient list.
Thanks for the explanation.

As far as human delays go, we have no difference of opinion.  A couple of
the mailing lists that I manage used to have significant delivery delays
for some users, apparently caused by the behavior you describe above. I
fixed the problem by dumping Sendmail in favor of Postfix.  Its queue
manager is quite efficient (see http://www.postfix.org/qmgr.8.html for
details).

BTW, I hadn't heard of fastmail before.  Is it similar to bulk_mailer
(ftp://cs.utk.edu/pub/moore/bulk_mailer/)?
