Sendmail help

[John Macdonald]

Is there a good reference anywhere for sendmail?  (I checked,
O'Reilly does not have a Nutshell book that covers it.)

I'm trying to use it for the first time to set up a site with two
systems (a Sun 3 and a MIPS) connected by Ethernet&TCP/IP, where
one of them has a modem and uucp connection to an outside system.

I have set it up so that the machine with the modem uses TCP/IP
for known local machines (currently just the one), delivers local
stuff locally, and uses the outside system to resolve anything else.

If someone has a sendmail.cf that fits this situation, I'd be happy
to receive a copy.

(They don't have a domain name yet, but that is no problem for
the moment.)

I have the Sun sysadmin manual, and it has a fairly long section
on sendmail, but it is missing a lot of connection between the
description of low-level items in the sendmail.cf file and the
high-level description of the sorts of things you can do with
sendmail.

At the moment, my problem it that lots of large messages just
sit in the queue and are never passed on, in one case to lmail
(it came from a remote machine) and in the other cases to uux.
There are some descriptions of options that control penalty
factors for priority, but never a description of what priority
really means (in terms of how it affects *when* a piece of mail
will actually get processed - it does say that a higher priority
number means a heaavier penalty.  (In actual operation it generally
seems to choosing between three choices - a fair number of small
messages are processed immediately, a small number of "intermediate"
sized messages are queued for a while and then processed, and a
large number of large messages get queued forever (a week so far)).

I have also tried using the debug command line option, trying to
run it against a specific queued element, hoping to get so idea
of why the items a staying on the queue, but that just seems to
debug the non-existent message that it assumes that I'm piping in
to it, and complains that there is no destination specified.  The
reference in the manual that says "debug is very useful, if you
have source code you look around to find out what the codes and
levels actually mean" is rather discouraging to someone without
source code, but I just turned on everything and waded through
a huge amount of extraneous blather before I could figure that out.
(Source code would have allowed me to try and figure out the
queueing penalty algorithm too.)

I'm strongly tempted to dump sendmail and just use smail 2.5, but
if someone can convince me otherwise...
