Hi I have exim running on port 8900 and another mail server running on port 25. This mail server will be used to relay outgoing emails to exim. But somehow I am getting this error from exim 550, 'relay not permitted' when relaying email to exim. Is there any way I can configure exim to permit relaying?

All iedas are highly appreciated.

Add this to your config:

hostlist   relay_from_hosts = :

This will allow relaying from localhost and Change to whatever host/mask combination suits your network.

Is the local interface ip? – Joshua Partogi Oct 17 '10 at 8:31
The list following the equals sign is a colon-delimited list of networks (in CIDR notation) that you want to allow relaying from. – EEAA Oct 17 '10 at 16:27
