Re: Exchange 2003 does not receive external mail

ok, here's something that may help...
I'm on our internal network and I telnet to the external address, telnet
work fine. If I go to a PC that is not on our internal network and telnet to
the external address it does not work. Connection failed. It's not a
firewall issue, I disabled it to test... Anonymous access is enabled.

Most likely the cause is in your external DNS configuration - if you can
receive mail by telnetting to the external IP address, it confirms your
firewall NAT and ACLs are ok - you can get to SMTP from the outside. When
you use telnet by IP address, you are bypassing your external DNS.

I would recommend checking the external DNS configuration - you can use
something like DNSReport.com to confirm.

The only external mail exchange is receiving is manual telnet mail that I
did
as a test. The SMTP logs say nothing, diagnostic logginf for MSExchange
Transport shows generates nothing in the event logs.

Is Exchange receiving those messages?
- If no, what do the SMTP logs say?
- If yes, are they in the queue?
- Anything in the application event log?
- Bump up diagnostics logging for MSExchangeTransport. See if those show
anything.

Hello,
I'm running Exchange 2003 sp2. My environment is exchange on one box
and
the DC on another. All internal mail works and i can send externally.
DNS
seems ok, MX records seem ok. I can receive test mail when I telnet to
the
external address. External messages are getting to the server, I can
see
this
through a firewall log, but exchange doesn't process these messages. I
have
tried disabling the firewall and no luck. What's really weird is that
sometimes it will work for about 10 minutes or so, then all of a sudden
it
stops processing incoming mail. Any help would be appreciated, I'm
really
stumped on this one.

also, netdiag and dcdiag are all good and no errors in the event
viewer.
I've tired diagnostic logging, but not really too sure what to look for
here.
