I have problem with smtp relay errors where mail to one user name is ok to another fails in the same domain.
Mail received for abc.def@domain.com is rejected: “Attempt to relay mail to abc.def@domain.com rejected for policy reasons. Relays to recipient’s domain denied in your configuration.”
Mail to abddef@domain.com is accepted and delivered.
both addresses appear in the person document and are available in the $users view.
This is consistent at least. Mail to any address with a “.” in the middle of the name (abc.def) is rejected but with out the “.” is accepted.
What is wrong?. How can one address to a domain be accepted but another rejected.
Thanks in advance.
