Indeed, the .forward that might seem like an odd way to do it, but it has
worked for me for's real simple to do to and what's really nice
is there is no config needed to make it work!

What strikes me as really odd about this are 2 things. First this setup
was working 2 days ago before I went from FreeBSD 5.2.1 to 5.3 Beta2. The
other thing is that the 3 other boxes in the basement (2 OpenBSD & 1 Free)
are still functioning just fine with the .forward in place. If I change
the address in the .forward to my gmail account things work just fine on
the Free 5.3 box.
