IMRSS != IMRSS DSSL.  Both are off-line right now, actually, although
they'll be back soon.

IMRSS scans IP blocks to find hosts that have open relays.  We do not
use IMRSS.  IMRSS DSSL is akin to MAPS DUL -- it lists dial-up connections
(which should not be sending mail directly).  We use IMRSS DSSL.

I have a little .procmailrc set up to tag my own incoming spam with
which RBL's are matched, and I've seen that IMRSS does yield a large
number of false positives (non-spam mail).

ORBS and RRSS both (AFAIK) list a relay after spam has actually gone
through the host.

IMRSS is a political hot potato for some other reasons, like I _think_
they weren't notifying postmasters that they were listed at one point.


If you've heard bad things about IMRSS DSSL, please let me know.  I
haven't seen any problems with it, personally.
