Okey, thanks for pointing that out. The problem with such a solution is
that it would make the whole internet be able to send e-mail with the
new SMTP-server, if I don't disallow relay for that IP.
Oh well, I guess I will need to inform everyone about an hostname change
instead then. POP3 is easier since the IP doesn't matter much there.
Cheers
