Can't receive email on Exchange 2003

[AndyWatt]

Hi All,

We have just migrated a customer from NT4.0/Exchange 5.5 to 2003/2003. We can send email without a problem, but are unable to receive any email.

We are using an SMTP connector for mail. We have run exchdiag, which seems to suggest everything is working okay. We have telnet-ed to the server from both internally and externally and can connect, but still we aren't getting inbound email!

We would be most grateful for any suggestions as to how to diagnose what we have done wrong and how to resolve it.

Many thanks

Andy

Make sure your MX record points to the WAN IP and that port 25 is forwarded to the correct internal IP of the Exchange Server.

Another day...

We have determined (after much discussion) that the incoming email was being sent to the wrong IP address. We have contacted MessageLabs and now have mail routed to a DynDNS hostname that points to the WAN IP address of the router. So that is a step forward at least.

However we are still not getting any email coming in or going out now, despite it working on Saturday. /cry

After some more investigation we have discovered that we are receiving inbound email, but it is not being delivered to recipients. In fact if I send an email from administrator to administrator it does not arrive.

We suspect that the MTA is misbehaving. Any suggestions anyone?

Check in ESM that the Virtual SMTP Server is set up correctly.

Check that the services are all running correctly.

Can you send internally?

Hi Zel,

Got round it all in the end by re-installing Exchange Server. After that everything started behaving itself.

Everything is hunky-dory now!
