That's not quite right, I don't think, because if the sender uses
Squirrelmail on my server, his messages are accepted at places where they
are otherwise blocked.  Mine is a personal sever.  I am a newbie, but I'm
using Postfix/Debian and it is not an open relay.  I personally have not had
any problems being blocked anywhere, I've used dnsbl lookups and been OK,
and have used available open-relay tests and been OK.  We only have problems
when my non-US friend sends mail to the list (or to certain domains that
apparently have him or his ISP blocked).  This sender is a "good guy" - a
missionary that is only sending mail to his supporters - nothing
unsolicited.  His only problems are with AOL and one non-US domain.  Thanks
any other comments.  - john
