Hello. It is possible to use an alias domain for (pop3) login? (I hope, it is.) I have a domain example.com and a domain alias example.net. Mail to email@example.com is accepted and delivered to the mailbox of firstname.lastname@example.org. No problem here. But: I want to be able to use the address email@example.com (with example.net = alias domain) for pop3 authentication. How do I do that? Login with main domain is working: # telnet localhost 110 [...] user firstname.lastname@example.org +OK Password required. pass verysecret +OK logged in. Login with alias domain fails: # telnet localhost 110 [...] user email@example.com +OK Password required. pass verysecret -ERR Login failed. Hints are welcome. Thanks in advance.
