Stripping the Reply-To: fixes the immediate problem you were having,
but it doesn't fix the underlying problem, and it is a bad idea in

It is a bad idea in general because a user may send a post with a
Reply-To: which is different than From: and which may be required for
that user to receive a reply. For more on this, see for example

The underlying problem in your case appears to be that somehow in the
processing that delivers mail from your incoming MTA to Mailman, a
Reply-To: you header gets added to the message. The real solution is
to figure out where and why this is happening and fix it there.
