We have an sbs 2003 server, and i need to setup an alternative email domain. I have followed the instructions, put the mx record to the dns, altered the recepient policy, updated certain users email address settings, even restarted the server… but i can’t use the new email addresses from outside the network. i have sent an email to a new address, and i got back 5.7.1 SMTP relay access error message immidietely.
what did i forget to setup?
after this delivery issue is solved, i need to setup the clients so the users could send email from both email addresess.. how can i do that?
