Presumably the debian package maintainer has been notified about this?

What do you mean by "resends"?  All attempts Mailman does to
distribute a message to any list's members?

Ummm... this message says that something (running as user `list'
according to identd) tried issuing a

  RCPT TO:<root>

command after in a session originating from

I'm not quite sure why Mailman would try to send anything at all to
the unqualified address <root>, as Mailman shouldn't allow any
unqualified addresses to be subscribed to lists.

However, there seems to be a loophole in bin/newlist -- if you're
entering a unqualified address as list admin address, it is accepted.
I'll fix this shortly.

It goes without saying (or at least I think it _should_ do :) that
anyone using unqualified addresses as list admins *needs* to configure
their MTA to qualify these addresses for them (or at least accept them
unqualified).  In Exim 2.* this is done by means of setting
qualify_domain, qualify_recipient and
{receiver,sender}_unqualified_{hosts,nets} appropriately -- which I
believe you have neglected to do.

I can't see how this should have any effect whatsoever on what RCPT
TO: SMTP commands Mailman will issue.  Could you try to elaborate a
bit on the message flow of a Mailman-destined message on your system,
and why such a flow would make this setting necessary?
