Right now our sendmail.cf sends most of our offsite mail
to a relay via SMTP (csnet-relay over x25net if it matters).
I have the mailer properly configured to send letters
with multiple addresses all at once, and that works fine.

The problem is that when sendmail runs the queue it tries
to handle each item separately. If the queue consists of
all letters going to the same SMTP site, it will one by
one setup and tear down a series of connections to that
site. If the site is a busy one, it is likely that this
will fail before running the queue. If it is very busy
it may well fail after the first letter.

I don't see anything in the doc to help, but just in case
I am missing something, is there a way to make sendmail
send multiple letters from the queue with the same destination
with one SMTP connection?

One more related question. What I call the sendmail queue
looks more like a stack. If a smtp connection fails and
a letter is deferred, it appears to me that it will be
further down the list than mail sent later. If only one
letter ends up being sent per run of the "queue", and
new mail appears on the average of one per run, old
mail will be indefinitely postponed.

Is there a way around this latter problem?
