I run a exchange 2007 server which works fine. I have 2 different domains running which are accepted.
I would like to have one more domain. I already added the domain in the "accepted domains". I set up users and mailboxes for this domain.
Sending a Mail to this domain will cause an error " SMTP error from remote mail server after RCPT TO:<mydomain>:
host mail.mydomain.de [126.96.36.199]:
550 Relay not permitted
I dont know why it will not accepted. The other domains (2) are working fine. I did not find any differences.
