I wasn't going to reply, because it would just be another case of "no
win" ...
I will, instead, simply state that my ISP made clear a number of things
about the types of firewall protection they have:
1. The SMTP server will not "open relay."
2. If the need arose for me to telnet into the servers, for mail
tossing from foreign site [like when I'm stuck in the VA hospital], they
would consider giving me a username & password that would allow it;
without the username & password, it would not be possible to do.
3. Anyone who believes such to not be the case can attempt to telnet
into the SMTP server and see what happens. If [as I suspect] you can't
even get close using just "go-concepts.com," and you are bound and
determined to prove me wrong, please ask for the numeric address and I
will provide it. If you *can* manage to break in, then my ISP would
like to know that, and they won't get angry at you unless you also
decide to send out a spew of spam.
l.d.
