Two e-mails with the same smtpd ID?

Two entirely different e-mails with the same smtpd ID?  Can that be correct?  (Emphasis and identity changes made)

  • Got a call from an assistant to the recipient end user that the sender received a bounce today, and started looking in the logs for traffic involving that sender.

    After you've identified an instance, one way to isolate and view all the traffic involved in that particular e-mail transaction is to use the ID as your search criteria.  It enables you to see the whole of a transaction "en masse".  A lot easier than parsing through separate lines.

    Anyway, after doing so, I came across the items I posted.  I haven't previously studied a lot at smtpd traffic, but then, I haven't noticed two with the same tag before either.  Particularly since a bounce occurred and I haven't found any other reason for it to have happened.  Maybe it's legit and it queues them up as one transaction?  I don't know.

    Any ideas?
  • I don't know how all that works.   Is it possible that atty.com and company.com have email hosted by the same provider?
  • I believe that is the process id .... the queue id later in the logs shows that they are identified as separate emails to Exim.

    ETA: I could be wrong; but I do seem to recall seeing that happen before on my system with no ill effects.
