See http://lists.roaringpenguin.com/pipermail/mimedefang/2004-January/019541.html Also, note that Groupwise has had several security problems in its SMTP module over the years, and had a habit of taking the whole server down with it when it failed to interpret the standard correctly, plus its anti-relaying option didn't work for a long time, so anyone who was running it as their Internet-visible server was mad. I used it extensively in a previous position, and liked the main system (which was, and still is, much better than Exchange and Outlook), but I had it behind a Sendmail system. It will undoubtedly have improved in the last three years, but I still believe that anyone using a proprietary SMTP server as their main public interface needs a nice leather couch to lie on - would you make Exchange or Notes SMTP services visible to the whole of the Internet?
