      Hi all,

      Setup is: we have a server that does the spam checking running
      MailScanner / Spamassassin and of course postfix

      Mail is then delivered to a machine running MailEnable (where the boxes
      are held)

      We had a situation where the MailEnable machine went down

      *In the maillog of the server running postfix were:*

      Neither the original recipient or the original sender received
      notification that there was a problem or any form of bounce message. The
      original recipient also never received the email.

      My question is what happened to the email and the bounces and how can I
      change the setup so that if this occured in the future (i.e. the spam
      checking server can't communicate with the mailenable server) mail does
      not disappear.

      Thanks
      Kate

        Indeed. The original message was rejected with a permanent error
        ("550 5.7.1 Unable to relay"), as was the non-delivery notification.

        Configure the Mailenable system such that it doesn't reject mail
        with a PERMANENT error for conditions that you don't consider
        permanent.

        You can configure the Postfix SMTP client to pretend that permanent
        errors aren't permanent, but that introduces other risks.

          I heard back from MailEnable and it occurs when MailEnable can't access
          the boxes. This is ok and probably as it should be.
          When you say I can configure Postfix SMTP client to pretend that
          permanent errors aren't permanent is this something I could change
          temporarily (say for the time the MailEnable machine is rebooting) and
          then change back?
