    Delays in some outgoing email

    Locked

    by jspaz ·

    I a running Exchange 2000 with Outlook 2000 clients. We use an internet-based SMTP server. Periodically, an email will not reach it’s recipient for 8-24 hours. I can see that it arrives at our SMTP provider immediately, but can’t seem to resolve the reason for the delay. The vast majority of the mail gets delivered immediately. Is there a way to determine whether the problem is with our SMTP server or further downstream? Why is mail to certain locations being delayed?

      The simple answer to this is that the mail exchanger (MX) for the recipient’s domain is not online at the time you send the email. So your SMTP server will wait until such time as it can deliver your mail.
      If you want to monitor this you could write a list of the domains that experience this problem. Then set up a scheduled task to ping the mail exchanger for these domains and write the results to a text file. You will be able to see when they are online.
