I would like to point out, after much thought and discussion, I believe that completely blocking outgoing SMTP to be a bad idea. Here's the reasoning. I may be foo.com, a mail hosting service. My customers send and receive mail via me, but do not connect via me. I set up a system whereby only my users can send mail via me (magic elves or something, thats not important). In this instance, it makes sense to allow your users to send mail via me, if they are also my users. By blocking outgoing SMTP you are disallowing the possibility for someone to use my service, and not necessarily getting the gain that you wanted anyway. Its that nose face thing (watch what you cut off). Justin "No, I don't do mail" Newton ************************************************************** Justin W.
