    Just started getting the following error. I'm not an Exchange/Outlook expert,
    so I'm not even sure where to look at the Queues to see what is pending. We
    did change the IP address of the server last week, and ran the CEICW. Mail
    seems to be getting delivered, but this error worries me.

    Where do I start tracking this down ?

    THanks

    Alert on SERVER at 11/29/2005 4:35:13 AM

    A large number of messages are pending in the e-mail server send queue.

    Verify that you have Internet connectivity. If you can view Web sites
    normally, contact your Internet service provider (ISP) to determine if
    there is a problem with their e-mail server.

    You can disable this alert or change its threshold by using the Change
    Alert Notifications task in the Server Management Monitoring and
    Reporting taskpad.

  2. Hello Adl,

    Thank you for posting in the SBS newsgroup.

    According to your description, I understand that you received this Alert
    message "A large number of messages are pending in the e-mail server send
    queue". If I have misunderstood the problem, please don't hesitate to let
    me know.

    To narrow down this issue, please answer and perform the following
    questions and steps:

    1. First of all, as you mentioned "you have changed the IP address of the
    SBS Server last week", what¡¯s the exact problem symptom? Did you use the
    "Change Server IP Address" wizard to do this? You can launch this wizard,
    go to Server Management console -> Internet and E-mail -> Change Server IP
    Address.

    2. First of all, please refer to the following information to re-run the
    CEICW:

    a. Run the CEICW and go through the Internet and firewall option.

    b. In the Internet E-mail tab, please click to "Enable Internet
    E-mail".

    c. In the Email Delivery method page, please choose the correct
    email delivery method. If you need to forward internet email to your ISP
    Smarthost, please input the Smarthost address correctly. If you use DNS to
    route emails, please choose this option.

    Note: If you choose to forward emails to the ISP's email server (smart
    host), you need to type the FQDN of the ISP's email server. If your ISP
    provides you the IP address of their email server, for example,
    12.34.56.78, you should type the IP address as "[12.34.56.78]" (without the
    quotation marks) on the connector's properties page.

    d. In the E-mail Retrieval Method page, specify to receive e-mail
    using one or both of the following methods:

    - POP3 Mailboxes
    - Exchange

    Click Next.

    e. In the E-mail Domain Name page, enter your registered e-mail
    Internet domain name, (i.e. domain.com). The e-mail domain name should
    match the mail exchanger (MX) resource record maintained at your ISP. This
    must be a registered Internet domain name.

    f. If you are using the POP3 Connector to retrieve incoming email, in
    the POP3 Mailbox Accounts page, click Add and add the appropriate POP3
    mailbox accounts, then click Next.

    g. Input the correct information in the rest page and finish the
    wizard.

    For delivering the internet emails, if you have hardware router, you should
    make sure the Outbound TCP port 25 is opening. For your ISP configuration,
    you ISP should allow TCP port 25 outbound communication.

    If your SBS server uses ISP smarthost, I would like to bring the following
    article to your attention

    3. If you're using POP3 connector, it will also cause open relaying.
    Please check whether KB 835734 solves the problem.

    Business Server 2003

    4. please check in which queue the emails stays (you may not see it if it
    is delivered). To check this:

    1). Start Exchange System Manager.

    2). Use the following path to locate the queues you want to check:

    Servers\<ServerName>\Protocols\SMTP virtual Server\<SMTP virtual
    server>\Queues\<Queue>

    5. Enable Diagnostic Logging to determine the root of the transport
    issue. To enable Diagnostic Logging on the MSExchangeTransport service:

    1). Start Exchange System Manager.

    2). Navigate to the server object.

    3). Right-click <Server object>, and then click Properties.

    4). Click the Diagnostic Logging tab.

    5). Under Categories, click MSExchangeTransport.

    6). Under Logging Level, choose maximum for all the items. Restart the
    server.

    7). Let a user send an outbound message and copy all Exchange relative
    events in Event Viewer.

    For more information regarding how to troubleshoot Exchange problems,
    please refer to the following article:

    General troubleshooting for transport issues in Exchange 2000 Server and in
    Exchange Server 2003
    http://support.microsoft.com/?id=257265

    6. Enable SMTP logging and gather SMTP log to troubleshoot the issue:

    A. Open Exchange System Manager, expand Servers -> <Server name> ->
    Protocols -> SMTP, right-click "Default SMTP Virtual Server" and click
    Properties.

    B. Under the General tab, check the option "Enable Logging".

    C. With "W3C Extended Log File Format", click "Properties".

    D. Under "General Properties", make sure "Use local time for file naming
    and rollover" is CHECKED.

    E. Switch to the "Extended Properties", and then select to enable All the
    logging Options.

    F. Click OK to apply the modification.

    G. Right-click Default SMTP Virtual Server and click Stop.

    H. Right-click Default SMTP Virtual Server and click Start to restart the
    SMTP server.

    I. Reproduce the issue, repeat step G to stop Default SMTP Virtual Server,
    copy out or zip the SMTP log files in the
    "%systemroot%\system32\logfiles\SmtpSvc1" folder, and then restart the
    "Default SMTP Virtual Server".

    I appreciate your time and cooperation. If anything is unclear, please feel
    free to let me know. I am looking forward to hearing from you.

    Best regards,
