  • Delay receiving email

    I keep getting reports from users that there is a significant delay in receiving email from certain senders. This is an intermittent problem and has been difficult to troubleshoot. My Exchange 2003 server seems to be operating normally as when I track these delayed messages they are being delivered to the user's mailbox as soon as they hit the server. Could this be a firewall or ISP issue? Any help is greatly appreciated.

    Take a look at the headers for one of the purportedly delayed emails and see what it looks like. The headers should show every host that the email was forwarded through along with the time.

      Re: Delay receiving email

      Thank you for the advice. Here is the header from one of the delayed messages. If I am reading it correctly, the message was sent at 15:23, was routed through yahoo's servers, and hit my server at 10:53 the following morning. I have replaced some info with **** for security. Does anything jump out at you? Thank you!

        Re: Delay receiving email

        As a follow up, I ran a telnet test to my mail server using a yahoo address as the sender. The test ran fine and I received the message right away with no delay. This might be a stupid question, but could this be a DNS related issue?

          Re: Delay receiving email

          It could be a DNS problem, if your name servers were unavailable or having problems answering queries then the Yahoo server would queue the email and re-attempt delivery at predefined intervals.

          The headers look exactly as you described. The sender sent the email at 15:23 PDT, it went through Yahoo's email system, and was dlivered to your email server at 10:23 the next day.

          Your server has a timezone offset of -0700, which is PDT, right? So the sender and the recipient are in the same timezone? The reason I ask is because the Yahoo servers seem to timestamp the email with UTC -0000.

              Thank you all for the help. You'll have to forgive me as I'm new at this but what could be causing the timezone mismatch? I have verified that the server and firewall are both set to PDT. Should something be set to UTC? Thanks again!

                the outside server is set to UTC..
                you just need to make the manual calculation in your head for the timezone offset
