If you can identify a feature common to all such connections, use that rather
than the remote-ip in your greylist DB tag. Also, if you know the always retry
like real MTAs should (and some spammers don't), you may as well whitelist them.

Or, autobuild a DB of known-retrier IPs, and use that to whitelist.
