Hi all,
I am having an issue with a secondary accepted domain name. The DNS MX is set correctly and I have tested outbound email which is fine. I can telnet to the server through mail.secondname.com so port 25 is passing fine, but I get the following error when I try send an email to any addresses.
554 5.1.2 Recipient address rejected: User unknown
The accepted domain has been created and of course I have checked users have the correct aliases as well. I am at a complete lose end here. Any suggestions would be much appreciated.
