You're right. That's a good question. Why is mailman
receiving these messages?

Here's the message that gets sent back:
Your mail for [EMAIL PROTECTED] could not be sent:
        no list named "blah" is known by lists.foo.com

For a list of publicly-advertised mailing lists hosted
on this server,
visit this URL:
        http://lists.foo.com/

If this does not resolve your problem, you may write
to:
        [EMAIL PROTECTED]
or
        [EMAIL PROTECTED]


lists.foo.com delivers e-mail to registered mailing
lists
and to the administrative addresses defined and
required by IETF
Request for Comments (RFC) 2142 [1].

Personal e-mail addresses are not offered by this
server.

The Internet Engineering Task Force [2] (IETF)
oversees the development
of open standards for the Internet community,
including the protocols
and formats employed by Internet mail systems.

For your convenience, your original mail is attached.

Roles and

What can I change so that nothing gets sent?
