I certainly understand why you would think this given your
observations, but I have never seen this problem from Mailman, nor
have I seen any report of it other than yours, so I'm inclined to be
Here's a suggestion for a test. Presumably, your current MTA that
delivers to Mailman has aliases (or equivalents) to hand off incomming
mail to Mailman. In particular, the posting address for listname has
listname(a)example.com: "|/usr/local/mailman/mail/mailman post listname"
The path to mailman/mail/mailman may be different, but assuming there
is an alias like this, you could change it temporarily to something
listname(a)example.com: "|tee somefile|/usr/local/mailman/mail/mailman
i.e. you could capture a copy in somefile of the incoming message as
delivered to Mailman. Then, by comparing this copy both to what you're
sending and to what Mailman sends, you should be able to pinpoint
where the problem is.
