Please have a look at the below, it can be any of the below issue.


1)       Network connectivity issues

2)       You might be blocked by Remote server

3)       Try to telnet 25 to the remote server and see what the response
you can see?

4)       Do you use ISP Smart Host for delivering Emails or you got own
SMTP server?

5)       Finally Check the DNS. ( check FQDN is valid for SMTP Virtual


If the issue will not resolve please increase the Diagnosis logging for
MSExchange Transport.

Hi guys,


Not quite sure why this is happening. But we can send emails to people
ok, but we are having problems from a particular domain. Other domains
can send to us ok.


When we send a mail to the domain it arrives ok, but users can not reply
to our message. They keep getting the 4.4.7 NDR with message delayed and
then timeout.


If anyone can point us in the right direction it would be helpful, cos a
lot of steam and trouble is brewing over this.
