Depends on how they are doing it, and why IMHO.
We will block reception or transmittal of any mail that originates or is
destined to a mail server (MX record for the domain) that is known to be an
open relay. We consider an open relay to be a misconfigured (and likely
compromised) system. It is our right to not allow our server to come in
contact with such systems, as any contact with them is almost certainly
going to transit spam. Bear in mind that it only blocks mail traveling
through OUR server.
Don't try and say there are valid reasons for making a mail server an open
relay, there aren't. Period. No valid reason, ever.
Our method of determining an open relay is the ordb database, as well as
mail-abuse via a "DNS" lookup to their databases. It is completely
voluntary, and only affects what systems MY mail servers talk to. Both
organizations have proven to be pretty reliable in checking before putting a
server in their database, and getting it out quickly once the server admin
decides to become just a tiny bit responsible.
If you are talking about other things than open relay checking, I'd like to
know the specifics....remember, if the ISP is a responsible, reasoned admin,
he has every right to block traffic through his servers in the interest of
protecting his network - that's their sworn duty after all.
