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 server)


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.
