<Well, that certainly was the way it worked under Red Hat 7.3.... but
<not any longer. And while I'm an idiot when it comes to sendmail
<(and I actually like it that way), I just verified it too, er, the
<behavior, not my idiocy...no verification needed on the latter.
<
<RHEL3+ switched to this mail submission agent (i think that's what
<it's called) model. You have a separate sendmail.cf file for
<SUBMITTING email that for TRANSPORTING email. Look in /etc/mail.
<submit.cf is for sending/submitting email for delivery. sendmail.cf
<actually handles the transport.
<
<Local mail does NOT get delivered if sendmail is stopped AND
<submit.cf exists. I believe (and take this with a huge fat grain of
<salt) that if you remove the submit.* files that behavior reverts to
<the old RH7.3 ways... I think I saw that somewhere but it's 2am and
<I'm in NC...so it's way late.
<
<Now, before you freak (like I did) about running sendmail on a
<non-mail server, the line (in sendmail.mc) :
< DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
<means that sendmail only listens on localhost and doesn't even open
<a socket on any interface other than localhost.
<
<By the way, it's yet another of Red Hat's "oh we are changing this
<and not really going to advertise it anywhere" improvements. Sort
<of like Qlogic HBAs in RHEL4. But that's yet another late night
<rant I'm just going to shut up on.
<
<Hope that helps.

Ok, so based on your hypothesis regarding the submit* files, what would be
the appropriate approach for resolving this? Should I rename the submit
files to submitarchive* or should I be making some other type of
configuration change, such as running sendmail but configuring it to only
listen locally?
