Then it is not a dns problem, and it shouldn't be a hosts file either.

Instead of:

Try to do it giving the same domain name you use for email - then it
should try to connect using the eth0 ip address instead of the 127... one.
Even better, try from some other machine.

You should have a look at these entries in "/etc/sysconfig/postfix"

## Type: string
## Default: ""
# Comma separated list of host-/domainnames for which postfix
# should accept mail for.
# localhost and the own hostname is appended automatically

and then run suseconfig.

There is also a setting you can use for increased verbosity when debuging:


where that "someserver" would be the one email is coming from.
