I have to second that... In the early days when spammers were just
getting started, we started using some RBL's at the MTA level. ORBS
was one I believe. Then they went away and started tagging
everything as spam, and of course we started rejecting everything.
Lesson learned - we will not depend on any external RBL as an
absolute pass/fail test ever again :) We use greylisting on the
secondary MX's, but everything goes through SA eventually before
entering our internal mail system. Works great.
Most blacklists I know of that have gone away in the past set DNS to
return 127.0.0.2 to ALL requests that came in. Most of the email lists I'm
on received posts by other list members with reguards to the list going
away. I would speculate that was the reason your messages started tagging
as spam.
One such list I remember was ordb.org.
ordb.org RIP 12/31/2006
dorkslayers.com RIP 9/15/2003
osirusoft.com RIP 8/20/2003
orbz.org RIP 3/25/2002
orbs.org RIP 6/3/2001
And that's just from this millenium. ;)
Returning FP to ALL requests is the fastest way to wake up brain-damaged
sites that don't get the clue.
ordb.org, osirusoft.com, orbs.org - those were ones we used IIRC.
Guess we didn't have a clue then. As mentioned earlier, for our
setup anyway, it is unwise to pin pass/fail on RBL's. They can be
wrong, or go away.
