Hi,
anyone here who has experience with greylisting and the linux-kernel
list? I want to configure greylisting on my server but I don't know if
this setting is compatible with the list here.
What I want to avoid is a massive bounce because of that! So please give
me feedback, if greylisting is a problem for the list.
Cheers,
Michael Obster

Greylisting relayed traffic is useless. Greyslisting is also expensive (delays
and bounces) so probably that's not what you want. Anyway if you know what
you are doing ;-) take a look at this:

OS based greylisting is a compromise. Gives great results with minimal costs
to most of incoming traffic.

If you absolutely need to graylist (I have my doubts about it's
effectiveness) then whitelist vger.kernel.org.

Any half-sensible greylisting implementation would be exempting
vger.kernel.org as soon as it's observed to retry its _first_ mail,
anyway.
Greylisting done _stupidly_, where it keeps delaying mail from a given
host even after it's known to queue and retry, would be a problem. But
done sensibly it's fine.
