  • SBS Exchange 2003 - POP3

    Hi

    I have a question about the POP3 connector on SBS 2003 Exchange.

    The minimum schedule interval for getting emails is every 15 minutes. My customer is finding this very annoying. Manually forcing the POP3 connector to "retrieve now" is too cumbersome for him (furthermore, I don't want him touching the box!).

    Is there any way of shortening this interval? Can you force it to retrieve via a script, for example?

    Any suggestions welcome.

    Thanks

    You cannot change the interval to less than 15 minutes with the native POP3 connector.

    You have two choices.

    1. Third party POP3 connector.
    2. Get email delivered by SMTP.

    The preference is the second. This gives you more freedom with regards to antispam and antivirus techniques and is how Exchange was designed to operate.
    The POP3 connector is not designed to be a long term solution, but to aid the switch from ISP POP3 mailboxes to SMTP delivery.

      Thanks mate. I normally deal with very small businesses and independents and this customer is my only domain network, so I have limited knowledge on such things. So, please excuse any "dumb" questions!

      He is a small customer, only 5 workstations and communicates to the outside world with a basic ADSL connection (no fixed IP).

      Does configuring SMTP need a fixed IP?

      With a 3rd party s/w, is there an option in Exchange to connect to a 3rd party s/w?

      I realise you can't change the native POP3 to less than 15 mins, but as you can force it to "retrieve now" manually, I was wondering if that could be automated in any way?

        I only do one thing with POP3 connectors - remove them. I haven't used any of the third party POP3 connectors so cannot comment on them.
        Most of them operate in the same way as the native POP3 connector, in that they collect the email then drop them in to the pickup queue of the SMTP server on the Exchange server, and Exchange processes them as normal.

        Technically you need a static IP address for SMTP delivery.
        However you can work around that quite easily using a dynamic DNS account.
        You sign up for a dynamic DNS account, install one of the tools for keeping the account up to date on to a server, then set the MX records to be the dynamic DNS host name that you have chosen.

        I ran an Exchange server at home for almost three years before I ditched the ISP for another one that gave me a static IP address.

              Hi Jeremy,

              Thanks for the link. I have a basic understanding of SMTP and POP but wasn't sure about the context in which it was referred to in this scenerio.

              I will do some more reading, and if I can't find the answer start a thread.

              Keep up the good work.

              Simon

                Thanks for the info everyone.

                I'll try out some things on a test rig I have set up.

                Cheers.

                  Hi, this is the answer for what you need.
                  Dont remember where i got it from.


                  SBS POP3 Connector Polling Interval

                  The minimum level you can set through the GUI is 15 minutes.
                  This is how you can change this through a registry setting: ScheduleAccelerator.
                  Remember, this connector is only available for a Small Business Server !



                  1. Locate and then click the following registry subkey:
                  "HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/SmallBusinessServer/Network/POP3 Connector"

                  2. On the "Edit" menu, point to "New", and then click "DWORD Value".

                  3. Type "ScheduleAccelerator" (without the quotation marks) as the entry name, and then press ENTER.

                  5. On the "Edit" menu, click "Modify".

                  6. In the "Value data" box, type the value that you want, and then click "OK". To determine the polling interval, the value that is configured on the "Scheduling" tab in the GUI is divided by the value that you type for the ScheduleAccelerator entry.

                  For example, if a 15 minute interval is specified in the GUI and you set the value of the ScheduleAccelerator entry to 3, the connector will poll ever five minutes.

                  7. Quit Registry Editor
