If your `default configuration' was that your mailserver was doing
direct delivery, digging destination-domains' MX records out of DNS
and connecting directly to those servers, then I guess the ISP reps
could be telling the truth: maybe they're not blocking you at the
router, maybe your IP address got onto a blacklist and the receiving
SMTP servers really just refuse to talk to you?

Alternately, they /could/ be lying; maybe inadvertently--it's not
exactly a lie /per se/ when they say that they `don't filter Internet
access at all' if they can just redefine what "Internet access" means
(and, in parlance with most customers, they can probably get away with
redefining "Internet access" as meaning `web sites').
