Likewise here, though nobody has yet asked to be taken back out of
it. (I think they are too busy weeping with joy.) Since my greylist
whitelisting feature is just a big Exim "or" condition, it's easy for
me to add in specific localparts (or even specific localparts and
combinations of whatever else I know at recipient address verification
time).
I greylist for 5 minutes, and the results seem pretty good. Even the
spammers who do spinning retries immediately seem to give up after 2
or 3. It seems to be common for legit servers to do a retry at 10-15
minutes, which is not too bad. Still tuning....
PS:- Most of the sample Exim greylisting starting points are
understandably for Exim4. For reasons that are not important here, I
did mine for Exim3 (using embedded perl and a backing MySQL database).
If any Exim3 users are interested in details, drop me a line.
