1:1 aliases for relay domains not possible

[kava1189]

Hi there.

I'm facing with the following problem.

We have an older postfix server and a new one. Both with postfixadmin.
The old one has postfixadmin 3.2 installed and there I can add aliases for relay domains with no problem.
(Listed domains are setup as transport type relay)

f.e.:

master@example.com -> master@example.com

On the new one with current postfixadmin release I can't add an alias for the relay domain because the alias may not point to itself.
When I install on the new postfix-server the old postfixadmin 3.2 version I'm able to add the aliases.
Both servers are relay for final mail servers so they don't process any mails local.

I am doing anything wrong here?

See #358

You could edit https://github.com/postfixadmin/postfixadmin/blob/master/model/AliasHandler.php#L421 and stop it from blocking you?
