IP: The age of new blacklisting is upon us (not related to homeland defense)

[Increasingly, the fight against spam is resulting in automatic blocks
against innocent parties. Here's a message from a system administrator
explaining what happens - sooner or later, either as a blocker or a blockee,
*you* too will experience it. Sigh.]

We are increasingly having a problem with outgoing email being rejected
by the receiver's domain (eg. see below).

This is happening because our mail server has been blacklisted by
certain spam-monitoring organizations. We are on these lists because the
server is configured (by necessity, for now) in a way that a malicious
person could use it to relay spam.

Sysadmins at certain domains are starting to use these lists (eg.
http://ordb.org/, http://orbz.org) to filter incoming email. Messages,
spam or not, from hosts on the list is summarily bounced. To me, this is
a rash and stupid action on their end, but there's nothing I can do
about it.

The solution is for us to get off these lists by securing our server.
Changes on our side will be forthcoming in the next month which will
address the problem. These will likely require you to make some changes
in the configuration of your mail reader. Watch for future instructions.

For now, it may be necessary to use an alternate email account when
mailing certain outsiders. We apologize for the inconvenience.
