There is no way for milter-greylist to distinguish two different
messages with an identical ip-from-rcpt combination.

In that particular situation, one message will generate the greylist
tuple while the other will count as a retry.  As soon as the greylisting
period has expired, one message will generate an autowhite tuple while
the other will get a pass.

The behaviour reported by OP is probably a bug and not even a weird one
since I often get ``X-Greylist: Delayed for 00:00:00 (...)'' for dacl
delayed mails.
