I write my own greylisting plugin some time ago due to problems I had
with the one included. I posted it on this list, but never got any
comments on it.
See

I've been using it on my firewalls since september with no problems
at all.

I've been experimenting with the greylisting plugin a bit lately,
and I've noticed some odd behavior.
It seems that mail for domains that aren't in rcpthosts that would
normally get a 5xx message and get rejected are hitting the
greylisting. As a result, they get a 4xx rejection first, and then
after the transition from grey to white, they get a 5xx. I've
included log lines and transcripts below. I'm wondering is this
the intended behavior or should this be counted as a bug?
