The bulk of the time in smtpd_mumble_restrictions happens between
these two logfile records:
smtpd[pid]: connect from name[addr] (reverse/forward name lookup completed)
smtpd[pid]: queueid: client=name[addr] (first recipient accepted)
The delay-'a' value measures the time since the incoming queue file
was created, i.e. when the first recipient was accepted.
This is why most rejects are logged with NOQUEUE as the queue ID.
