      Hi Mouss,

      I've just replicated the issue right now, from /var/log/maillog:

      Feb  1 21:26:38 mail postfix/cleanup[19777]: 55E6C148049: hold: header Received: from [] (unknown [])??by mail.ddblocal.com (Postfix) with ESMTP id 55E6C148049??for <ragestre@...>; Sun,  1 Feb 2009 21:26:37 +0800 (PHT) from unknown[]; from=<jan.gestre@...> to=<ragestre@...> proto=ESMTP helo=<[]>

      postmaster@... exists and has an alias jan.gestre@..., all emails for the postmaster gets forwarded to this account. This doesn't happen when I used a webmail client.

      you need to check the postfix logs (/var/log/maillog or
      /var/log/mail.log or the like), not bounce messages.

      for obvious reasons, postfix won't tell everything to an smtp client, so
      you won't know what is really happening by looking at a bounce message.

      but from the bounce message, I see that <postmaster@...> is
      "unknown". This is bad. if this is one of your domains, make sure mail
      for postmaster is accepted and delivered. In general, people create an
      alias for this address (alias_maps if domain is in mydestination,
      virtual_alias_maps if domain is virtual).
