Exchange telnet SMTP Banner corrupt

I am having the following Exchange 2003(Server 2003 SP2) current on all hot fixes.


telnet mail.mydomain.com 25

I get the following...

220 ***************************************************************200**0**2****

**0*00

I have changed the FQDN in the Virtual SMTP Server, restarted the service and the server itself and the problem continues.
Is there a way to reset the Virtual SMTP settings?
Any ideas where this is coming from?

Thanks,
I will follow up.

Hi hansonebad,
Not a firewall issue is it?  Do you get the same response when you telnet localhost 25 on the exchange server its self?

Cheers!

Internally the telnet is fine.  There have been no changes to the firewall.
rrusteanCommented:
I only ask about the firewall because i had a similar problem which ended up being the watchguard firewall not passing on the smtp traffic properly.

If internal telnet works ok then this could suggest a similar issue.

We are receiving and sending e-mail, both internal and extenal.
When I run DNSREPORT I recieve the following warning:

mail.mydomain.com claims to be invalid hostname '***************************************************************200***0*2******0*00':
   220 ***************************************************************200***0*2******0*00

I double checked the firewall settings and nothing has changed.

When I telnet interally to the local server name, the response is correct, with the correct SMTP greeting.
When I telnet from outside, i get the above error.  I suspect it is something in the metabase?

the issue that you are facing is mentioned in the following Kb article

Changing the firewall has fixed the problem.
However, what concerns me is I had to change the firewall to make it work, when the firewall was not touched.
Reading further into the Cisco & Microsoft KB articles, this response appears to be by design.
Before I close this, the warning mail.mydomain.com claims to be invalid..etc.  important?

PS the change to the firewall was
no fixup protocol smtp 25

im guessing that that is a client error where it can't connect to the server.  Don't quote me on that though.  

Glad you got it fixed.
