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 overwhelmed.
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? -Tom !DSPAM:4d40fdfb32711497852214!
