Subject: Re: Spam Control Considered Harmful [....] The difficulty in the latter is finding a way to determine what SMTP servers they are supposed to have access to and then implementing that in a router access list.
There should be no difficulty at all in doing this. If they dial into your network then they use your outgoing mail relay server, and yours alone. Period. (Unless you have some kind of agreement in a roaming system where you authenticate your own users to someone else's dial-up and vice versa, in which case you only allow the user to connect to the the "home" ISP's mail relay host(s).) -- Greg A.
