Good advice, for sure.  Fortunately in this case I have no interest in
debate.  I've posted my $0.02, and I'll let people take that for what it
is....

There is something to be learned here.  Blocking e-mail based on
ANY single service is likely to be a disservice to you and your
customers.  I have yet to see a "mistake free" block list from
anyone.

Tools such as SpamAssassin allow you to score e-mail based on
responses from many services, including SORBS.  Make sure you're
using 6+ services, and at least two, and preferrably three must
agree before you toss the mail as spam.

So when you contact that mail admin, tell them to remove whatever
DNSBL's they have at the SMTP transport level and let SpamAssassin,
or a Barracuda, or other similar tool make decisions based on
corroborating multiple sources of information.
