        I believe that I have made some contributions to the development
of postfix from some fairly early days, and you will also find my
name listed amongst the reviewers of _sendmail_ by Bryan Costales, as
well as in the sendmail CHANGES file.

        I have since made some further suggestions to both Wietse and
Eric on things that I believe could be improvements at the largest of
sites (based on my experience at AOL) but also useful at smaller
sites, and so far they haven't been accepted. I believe that as time
goes on, they will come around to the ideas I suggested to them back
in 1997 and 1998, and one day we will have these improvements as well.

        Sorry, I think you're going to have to wait for LISA 2000.

     Unix is like a wigwam -- no Gates, no Windows, and an Apache inside.
      Unix is very user-friendly.  It's just picky who its friends are.
