Irgendwie hat deine Namensauflösung einen Hau:

$ host htw-dresden.de
htw-dresden.de mail is handled by 20 rmx4.rz.htw-dresden.de.
htw-dresden.de mail is handled by 20 rmx5.rz.htw-dresden.de.
htw-dresden.de mail is handled by 20 rmx6.rz.htw-dresden.de.
htw-dresden.de mail is handled by 10 rlux45.rz.htw-dresden.de.

$ host rmx4.rz.htw-dresden.de.
rmx4.rz.htw-dresden.de has address 141.56.16.134
$ host rmx5.rz.htw-dresden.de.
rmx5.rz.htw-dresden.de has address 141.56.16.135
$ host rmx6.rz.htw-dresden.de.
rmx6.rz.htw-dresden.de has address 141.56.16.136
$ host rlux45.rz.htw-dresden.de.
rlux45.rz.htw-dresden.de has address 141.56.16.45

Geht alles ohne v6

Was sagt "postfix check"
