[CentOS] problem talking to server postgrey/socket: Permission denied

[Dirk H. Schulz]

Hi folks,

I have installed postgrey from the rpmforge repo, but it does not work well 
with postfix from CentOS 5.2: I always get the error:

warning: connect to postgrey/socket: Permission denied
problem talking to server postgrey/socket: Permission denied

But the permissions on the socket seem okay (postfix could write to it):
srw-rw-rw- 1 postgrey postgrey        0  4. Okt 14:48 socket

I also tried "restorecon -R /var/spool/postfix/postgrey", but that did not 
change anything, either.

Googling does not show anything recent and helpful. Any hint or help is 
appreciated.

Dirk
