I have ISPconfig 2 and postgrey.
I am trying to whitelist a mailserver.
In /etc/postgrey/whitelist_clients it should be possible as I can understand.
But if I add a new row with the domainname of the sending server or IP adress and restarts postgrey I get this message:
Server configuration problem
There are a lots of simular rows in that file.
Has any body a clue?
