Paul, if you are still interested in greylisting you might consider a
solution that allows you to run SpamAssassin at SMTP time. I use
sa-exim (I believe there are others for different MTAs) and this allows
me to greylist based on score. For example, if the score is above 3
points then it is greylisted, otherwise it is immediately let through.
However, I would go with Chris's suggestion first and see if you even
need to bother. In our situation, we have to be very liberal on the
score to keep the FP's down, so we use greylisting on the uncertainties.

Greetings noob, I mean Paul :-)

SURBL rocks, but I'm a bit partial. The risks of FP are low, and we
to get them to zero. And anything reported as an FP is dealt with right
away, by numerous people. We take them very seriously.
Lookups are quick and getting quicker with each new mirror added. If you
have a LOT of traffic you can rsync to get lookups local. Directions are
the SURBL.org site.

I like everything but greylisting. It can have some issues when a timely
email is needed. Particularly with airline info. We've seen it here from
another SURBL contributor.

Complement is always better, but if anything I would remove greylisting
now. With SURBL I don't think you need it. But if you have the time and
don't mind waiting sometimes 20 minutes for some companies to resend,
I think you will be very happy with SURBL.
