Re: Need help finding tools to diagnose SBS/Exchange prob...

If you don't have an MX record in the external DNS, you wouldn't be able to receive emails. Try going through the logs and see what is happening to the messages you try to sent. The should give clues about the problem

Suppose one were to find, upon examination of DNS, no MX record? Would that
cause an Exchange server to allow receipt of mail from within and outside of
the domain, but only allow sent e-mail to travel intra-domain?

Respectfully, in my OP, I indicated that ISA is UNinstalled.

I did.

Again, if you would read my OP, you would note that I mention a
router/firewall.
Its logging is fairly limited, though. My burdens are many.

I'm a six-times a year, maybe more, kind of guy.

Under the circumstances, this may not be possible.

Most advice around this says that maximum logging degrades Exchange
performance. Are you saying otherwise?

Thanks for this. I'll check these logs right away.
