If you set up mail server with machines IP address some xxx.xxx.xxx.xxx  on  a LAN and got the mails you send bounced back with error 

mail for xxx.xxx.xxx.xxx  loops back to myself

then the problem is that when you set up mail transfer agent using yast, you filled in the field 'Outgoing mail server'.
This field SHOULD BE LEFT EMPTY if your server has own permanent IP address and can send  mail by itself.
