I just tried it, it didn't work. I think that mailertable takes precedence
over virtusertable. The mail gets delivered according to the destination
as defined for that domain to the exchange server.

It probably will work if you are delivering the mail locally (which I am
not) and sending it onwards.

As I said I didn't intend to use this for former employees' mail boxes.
Some addresses that never actually existed for this domain are
consistently being spammed. I though I'd use these addresses to train the
bayesian database, they will only get 100% spam as nobody else will send
mail to these addresses :)

Did that and also double checked if virtusertable feature was included in
my sendmail conf.
