This usually happens when a user sets up a forward from
user@siteA.com to user@siteB.com and at the same time
has user@siteB.com pointed back to user@siteA.com
I know of no easy way to know who is doing this. If you disect
the headers, you might get a clue about which machines have
the .forwards on them.
And then you can work back to which user on the list it is.
It is unlikely that your configuration at the list level is
causing this, unless you subscribed the list to itself.
Which is a common problem when new users say
subscribe list email@example.com
And you have open subscription.
a) check the headers of the message to see which machines are
bouncing the message and work back to the user.
b) check the list for obvious self references.
