  • Mail Stuck in Queues

    Hello all,

    I am having a problem with my exchange server it won't send mail and it stays in queues. Users within domain are able to send/receive email to each other. Users are able to receive email from outside domain (internet) no problem.

    I must miss configure exchange, any help greatly appreciated.

    Thanks,
    fixzit

    Based on the information you have supplied, impossible to diagnose.
    There can be any number of reasons why messages will stick in the queues. When messages are stuck there should be a message shown which can give an idea as to the cause.

      Hmmm...I am not sure what was really happening yesterday (no error message), this morning I restarted server 2003 and exchange 2003, then looked at Exchange System Manager all mails in Queues were sent and user got mail from administrator saying:

      This is an automatically generated Delivery Status Notification.

      THIS IS A WARNING MESSAGE ONLY.

      YOU DO NOT NEED TO RESEND YOUR MESSAGE.

      Delivery to the following recipients has been delayed.

      [email protected]


      weird...But all mails were sent go straight to junk mail. Try send an email again but got delayed a little and now exchange perform as normal. I am absolutely no idea what's goin on and there wasn't network problem.

      Thanks anyway

        That is a delay message. Doesn't help with diagnostics.

        However if you didn't see them in the queues, then it may well be the greylisting bug.

          Ok. You need to go into Exchange System Manager.
          Then you need to go into your Queues
          Then you need to find the specific email that is not being delivered.
          Then select that email.

          At the bottom of the ESM console, it will actually explain to you why the email is not able to be delivered

          If you review the following image (stolen from technet, sorry)


          you will see that one of the queues (DSN messages pending) is selected. At the bottom of the screen, it says "no additional information available"

          so what you need to do is select your queue that is not delivering mail (let's assume, using this image, that it is "mixed <--> AG3 routing group connector")
          Once you select that queue, down the bottom, it will say "host could not be found" or "connection timed out" or "connection refused" or any number of things like that.

          This is what we need you to tell us, so we can assist with accurately diagnosing your issues.

          If you can not find this information, or provide it to us, then I suggest you may be better off hiring an exchange consultant who can review the problem.

            I did look at the Queues (Mails aren't delivered) through Exchange System Manager, I also used Tools (Message Tracking Center) through ESM to find additional information on mails that were queued, but there weren't any information to help diagnose the issue. As I mentioned in my previous message all mails were sent to recipients (at [email protected]) after I restarted the Server. Now Exchange Server is performing as normal. Please note the image shown below after the issue resolved...Thanks anyway for your help.

              ok, so right now in the present situation, there's nothing we can help with.

              It's likely that Hotmail may have just been refusing access for a while, or something like that.
              Basically - the remote host didn't accept mail - it';s outside of your control, so let it go.

                Check with you ISP provider who is hosting you domain. I encountered the same problem a couple of weeks ago. For me it was a problem from their side.
