I have a small server, hosting a few domains for local non-profits. One
of them, a food co-op, just moved to a new location and got a new ISP
(AT&T). It seems that AT&T, the better to serve you, blocks port 25, so
the co-op is now unable to send email through our little server
(although, of course, their AT&T account works fine).

So, it looks like what I need to do is set postfix to listen on a
different port (587 seems to be recommended most) and allow tcp traffic
through my SonicWall on that port as well... and keep 25 for the others,
too.

Attached is master.cf, but it seems to not be paying any attention to
port 587 yet.
