Any advice on setting up DKIM to sign outbound mail on my vpopmail server?
I've spent some time looking around at various patches and I'm a little
I host about 150 domains, and I don't want to mess around with setting up
unique keys for each hosted domain. I'm fine with signing all mail using the
server's hostname and a single signing key.
I'm not really interested in verifying DKIM signatures on inbound mail, unless
it will significantly cut down on spam.
Any pointers on getting a simple setup in place?
