Milter-greylist

Hello all,

   I was asked if milter-greylist can (like SQLGrey allegedly can)
build greylisting filter by triplets IP/rcpt/sender first, but
after whitelisting a threshold amount of senders from the same
host (or domain?) - it would add the source host (or domain) to
the single-field whitelist and accept any remote senders to any
local recipients?

   I believe there is now only a toggle between such two modes
(either one or another), and the threshold value seems like an
interesting feature upgrade.

Thanks,
//Jim Klimov

Sure it would be interesting. You could make the thing more flexible
by allowing regex and subnet masks to be specified as tuple member
from an ACL action clause

Just pick a character invalid both in e-mail and IP address, and you
would get somthing like this:
racl greylist ... tuple "/@example\.net$/|user@...|192.0.2.1/32"

Of course the thing would be subject to format strings, hence the default
greylisting behavior would be: tuple "%f|%r|%i/32"
