Pegasus Mail & Mercury

There is an application Peer Guardian (http://phoenixlabs.org/pg2/) that is an excellent IP blocker. My idea was to install the app on the server that runs Mercury. In the list of blocked ports, I could add in IP ranges from countries that I would never receive mails from. Similar to using RBL lists. The advantage to doing it this way would be not only would it block incoming mails, but also outgoing. Any thoughts?

I've been keeping tracks of IP numbers of connecting users to an online service that we are running for a number of years as we used to have huge problems with unauthorized access attempts before. We have a well defined region where our users live, but, surprisingly, every now and then some of them log in from an IP in some quite different corner of the world. Email traffic does of course differ from web access, but people travel a lot these days, for business, vacation or whatever, and I believe that blocking by country would eventually cause some valid mail to be lost.

That may be true in some cases. But in mine, I will never receive messages from some areas of the world. The copy of Mercury I run is only for my and my wife's personal email. I access my email via a Palm 700wx and my wife through a local home network connection. So I shouldn't really miss any messages.
