Postfix 450 keeps Mailman looping; doc suggestion

Bug Description

When Postfix is configured to give transient (450) SMTP errors on local
error, and Mailman tries to send to an unknown local recipient, Mailman by
default keeps trying to deliver the same message every second. 450 is the
default on some Postfix installations.

This addition to README.POSTFIX might help other people in curing such a
problem.

I also think retrying every second is a bit blunt, but I haven't
investigated that - there's probably a parameter for it :)

cheers,
walter

Thanks. Not only did I add a blurb to README.POSTFIX, but I
fixed the retry-every-second problem.
