two copies (was Re: Qmail mailing list and ReplyTo:)

[Scott Schwartz]

Fact: SMTP does not guarantee that you won't see two copies of any
given message.  We all know this, right?  It's come up again and again,
and the fair comment is always that anyone who cares about that problem
will have their MTA set up to deal with it.

Irony: what's the point of complaining if your name appears twice
(perhaps indirectly) in the headers, when you simply cannot avoid
seeing some messages twice, for *whatever* reason?  So deal with it
quietly.
