That's not how greylisting works.  Greylisting is a scheme used to
eliminate spam.  The server knows what email addresses it's received
mail from in the last little while (say, the last month).  When it
gets a message purporting to be from someone not in its little
database (say, user@somewhere.com) it responds with a "try later"
message.  Legitimate mail will be delayed for a few minutes.  The
sending SMTP server will try again, and the message will be accepted
by the receiving server. That server will also record
user@somewhere.com as a "known" address.  The theory behind
greylisting is that a spambot either won't come back and retry sending
(it's going millions of messages to flood the net with, and can't be
bothered to retry mail) or will be found and shut off by ISPs before
the delay period expires.

I wouldn't think so.  More likely, you might have made a mistake in
your configuration parameters.  You might want to double-check your
python-list@.python.org subscription information in Mailman to make
sure you haven't inadvertently done something.  If the problem
persists, send a note to postmaster@python.org describing the problem,
and include a message (with all its headers intact) that demonstrates
the problem, as Chris did with the timestamps.
