I'd be interested in the answer to this too.

One thing though that I'd like to point out (to the poster) is that some
domains really hate it when you send mass emails to them. I seem to
remember a discussion a while back (where in I was edumicated) on Yaho
and AOL refusing bulk mail if the 'To:' was too long (as given to it at
the MTA level). So you need to be aware (if you aren't already) that
allowing huge lists to go to some domains may get them refused.

As this is the Mj list you might be better off posting the above in
Moongroup Mail Help list. Many there know sendmail intimately and if
those here can't help, they might. To subscribe:

Anyway, can't help you much but hope others here (or at Moongroup) can.

steps expecting different results.  I say it's proof that you're a
