[Mailman-Users] Problem with Micrososft Exchange 2003 SBS

please, anybody help.

One of our customers us using a Micrososft Exchange 2003 SBS. Yes, we dont
like it, too.
If this customer send a mail to two lists in to:-field, the mailman
distributes the mail correctly on both lists.
Persons, which are on both lists, get only one email. The problem is, that
the M$-server deletes one mail because they have the same rcpt and

We are providing over 200 lists and have no problems at all.
But this customers is sure, that this is a mailman-bug. I need support to
argumentate. Is here anybody who is working with M$-exchange? Or is here
anybody who can proof, that it should be no problem to have 2 mails with
same rcpt and same msg-id?

I found a thread in 2002 describing this problem but not solving. (
