That's okay - I don't have a problem with people sending me mail... 8-)

Yep - all okay.

Yep - it should be:

fakedom.com virtual:

The virtual map entries probably aren't needed, but I don't think
they're causing your problem. It looks to me like the "virtual" process
hasn't been started.

One thing I didn't mention in my previous posts (sorry) - you need to
create an entry in master.cf for the new agent. It should look
something like:

virtual unix - n n - - virtual

Also make sure there is a "virtual" binary in your libexec directory,
and that it has appropriate permissions.

A long message is better than a short one if it gives enough
information to diagnose the problem... 8-)
