Is this round the wrong way? I thought the discussion was about how users
on dialup connnections should use the Internet/have access to particular
service on the Internet. Whether they install their own mail server or not
makes little difference if they are on a dialup line when it comes to
blocking port 25 or not.


I quite like the idea of dynamic ACLs on the NASes to control whether the
customer may route out on a particular port or not - maybe that's the way
to work towards who can and can't do this (since the authorisation should
be enough to determine the trust given).
