I am having an issue with my mail server. I have 2 domains (r3dsystems.co.uk & r3cognition.co.uk) directing mail to the same mail server.
The problem is that some mail for r3cognition.co.uk cannot be delivered to the users on the mail server.
One contact has given us this output from a test he performed on our mail server. At a guess it means that the R3D Systems domain is taking presidents over the r3cognition domain but i do not know how to fix it. If possible i would like to switch the domains so r3cognition is the primary.
Telnet Response to port 25:
220 mail2.r3dsystems.co.uk ESMTP Postfix
If more information is needed let me know....
