I have 2 domains, domain1.com and domain2.com.hk
Both are running and working.
For domain1.com I can get mail on mx.domain1.com with my pop3 client.
For mx.domain2.com.hk I get "error: invalid user name or password" - when I try to login the mailbox from my pop3 client. Both is correct though. Webmail works outgoing, or internally within my VPS.
How can I fix that?
