Is there any known policy server or add-on, that will change

I guess it would be an adaptation of greylisting,
Anything like that out there?
Well, the first half was easy. I just made a few minor changes
to the example greylist.pl.
My greyhelo.pl works from the example test of: perl
greyhelo.pl (bunch of attributes)
But how to call it, only when a client fails
reject_unknown_helo_hostname?
The following does not work:
unknown_helo_hostname_tempfail_action = check_policy_service
unix:private/greyhelo
You'll have to call the policy service for each mail, and
recreate the reject_unknown_* tests in your policy server.
That's the only way you can detect temp failures.
So I'd have to test for nxdomain, against $attr{"helo_name"}?
Sounds easy enough. But unfortunately, beyond my skill set.
