Hello all,
I've ported John M. Simpson's qmail greetdelay patch to qmail-ldap.
Thanks. :)
here is the README file:
[...]
Coments are welcomed!
Any false-positives so far? I always listen that the
delay of SMTP greeting reduces a lot of SPAM incoming and that
it won't affect real MTAs, but as always, we find out that some
server uses really strange MTAs (or customizations), so if you
are using it, how is your impression about SPAM reduction and
false-positives?
I've been running it for only a couple of hours now, in a VERY small
system (only 30 mail accounts).
I'm planning on deploying it in some other larger systems after it
passes the stability test period. There really shouldn't be nothing to
it since it's a very small and simple patch. But i like to take things
slowly... =)
Even in this case, i've already got 14 hits so far!

9 hits from someone who wasn't willing to wait the mere 10 seconds i've
set for the delay, and 5 for others who were too impatient to wait. =)
