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,
