I did not realize this was already possible.  Should really RTFM a
bit more once in a while :).  How serious is the security issue
it describes in smtpserver.conf?  I am assuming that with a modest
100 users on the system doubling the router load should not be too
bad.  That is the impact isn't it?  Having to run the router once
during the smtp conversation and once more to process the email.
