Re: help me diagnose incoming SMTP problem

Tech-Archive recommends: Fix windows errors by optimizing your registry

1. Can you telnet to smtp locally on the Exchange Server? If not, make sure
SMTP service is running on Exchange server.
2. Check SMTP virtual server and make sure it's bound to correct IP
address(es) and port. The default ip binding should be "all unassigned"
3. Did you try telnet using hostname or ip address? If hostname, try ip
address as well. Does that work? If it does, you're looking at a name
resolution issue.
4. Try telnet from different machines - do you get the same result
regardless of which computer you try from?
5. If local telnet from Exchange works but not remotely, a filter's blocking
it enroute. Check if there are any firewall/ip filter settings on the
Exchange server itself.

Folks

I'm having a rather weird problem with a SBS 2003 installation of
Exchange. It's probably something pretty trivial but I can't figure
out what's going on...

In a few words the install is working just fine and on the e-mail side
we are using the exchange POP connector to retrieve e-mail from various
POP accounts.

However we plan to start using direct SMTP, i.e. receiving the mails
directly on the exchange server.

I have, I believe, done all the correct setup and to test it (before
modifying the MX records in the public DNS) I have tried to connect via
telnet on port 25 and manually generate a message.

However this is not working at all - the telnet session fails. Both
machines (the telnet client and the Exchange server) are on the same
subnet and I have no problem connecting on other ports (such as 80 for
the IIS server running on that very machine).

Any idea / troubleshooting tip would be welcome....

Thanks & regards
