Unable to send smtp mail to one recipient
Posted on 2008-10-15
I have a number of sites that I support all of which have SBS2003. In my own office I also run SBS2003 everything was fine until my own server crashed, I bought a new server and loaded it with SBS2003 R2 since then most of my supported sites work fine with mail being sent to me no problem, however I have 2 sites that can no longer send mail to me. They can however send mail to any other recipient via smtp. I have tried to telnet to my server via port 25 but cannot connect although they can connect to other mail servers.
I am banging my head on a brick wall now and cannot see where the break in communication lies, any help would be appreciated.
