Hi Dirk,

You're correct in your assumption that this is an SELinux issue. You 
need to write a custom policy to allow connection and writing to the socket.

How to do this is covered in the SELinux Wiki guide here:

http://wiki.centos.org/HowTos/SELinux#head-faa96b3fdd922004cdb988c1989e56191c257c01

and luckily for you, the example used is for postgrey/postfix so you can 
use the example provided.

Hope that helps.
