The bounced message bounced back, and this kept going back and forth. Kept us for a while to find this problem. The problem was that one alias forwarded to a mailbox and to another alias which forwarded to another mailbox and an external address. (like info -> box1, name; and name -> box2, external@domain.com) I noticed in another setup that exim did handle that situation without any troubles.
