Re: [Exim] Non root operation

`impossible' is a bit rash :-)

exim can be invoked from a super server such as inetd.
In this case, exim does not need to bind to a priv port.
As such, exim need never have root privs.

Another option would be to listen on a non-priv port, and have a port
redirector listening on port 25.

I suspect I could come up with others :-))
