    Hi guys,

    Have anyone found a problem similar to this one?

    We have two regional offices and host our email to an ISP (mycompany.com).

    -In one of our offices we are using the wk3 SB pop3 connector for our email
    (we send and recieve to and from external email addresses such as hotmail.com
    without any problem),

    -When we try to send or replay a message to some one to the other office
    (which obviously they're not in our server but have same email domain
    'mycompany.com'), they won't receive anything and we would get a
    Undeliverable: error message from the System Administrator saying that the
    e-mail account does not exist at the organization this message was sent to.
    It seems that it is trying to send it internally using the same domain name
    instead of go outside.

    -We tried all things possible and the only way to solve it is not using the
    pop3 from the server and use the regular pop3 from outlook and saving the
    message in the exchange server instead of a PST.

    If anyone have any other idea,I would really appreciate it.

    Best,
    Zurnch

  3. Hello Zurnch,

    Thank you for posting in the SBS newsgroup.

    Also, many thanks for Cris's great input.

    Cris is right on target, this behavior occurs when Exchange is configured
    to be responsible for the e-mail domain that the external POP3 mail server
    is hosting. When Exchange is responsible for an e-mail domain, it always
    tries to deliver mail that is addressed to that domain to a local
    recipient. If a local recipient with that e-mail address does not exist,
    Exchange generates the NDR message.

    To work around this behavior, use either of the following methods.

    Method 1

    Configure the SMTP virtual server in Exchange to send mail with unresolved
    recipients to the Internet service provider's (ISP's) mail server. To do
    this, follow these steps:
    1. Click Start, point to Programs or to All Programs, point to Microsoft
    Exchange, and then click System Manager.
    2. Expand Servers, expand Servername, expand Protocols, and then expand
    SMTP.

    Note If Exchange System Manager is configured to display the administrative
    groups, you must expand Administrative Groups before you expand Servers.
    Then expand the administrative group that contains the mail server.
    3. Right-click the SMTP virtual server, and then click Properties.
    4. Click the Messages tab, type the name or the IP address of the ISP's
    mail server under Forward all mail with unresolved recipients to host, and
    then click OK.

    The SMTP mail server that you specify must be the ISP mail server that
    receives messages for the POP3 accounts. This may be different from the
    POP3 server that you connect to when you download messages from the ISP.
    5. Right-click the SMTP virtual server, and then click Stop.
    6. Right-click the SMTP virtual server, and then click Start.

    Note In this case, any e-mail that local users send to recipients that do
    not exist on your server will be forwarded to the ISP's mail server.

    Method 2

    Configure the Default Policy in the Exchange recipient policy to use the
    local e-mail domain as the primary address, and then add an additional
    recipient policy to apply the POP3 e-mail domain to the local user
    accounts. This way, the e-mail domain for the local users will match the
    e-mail domain that the POP3 mail server is hosting, but Exchange will not
    be the responsible mail server for this e-mail domain.

    Be aware that the user accounts must be configured to be updated by
    recipient policies. This option is available under the properties for each
    user on the Email-Addresses tab.

    To configure the recipient policies in Exchange, follow these steps:
    1. Click Start, point to Programs or to All Programs, point to Microsoft
    Exchange, and then click System Manager.
    2. Expand Recipients, and then click Recipient Policies in the left pane.
    In the right pane, the Default Policy is listed.
    3. Double-click Default Policy, and then click the E-Mail Addresses tab.
    4. By default, an SMTP e-mail address that matches your internal domain
    name appears in the list of addresses. For example, if your internal domain
    name is mycompany.local, the address @mycompany.local will appear in the
    list. If the internal domain address is not listed, follow these steps to
    add it:
    a. Click New.
    b. Click to select SMTP Address, and then click OK.
    c. In the Address box, type the internal domain address, and then click
    OK. For example, type @mycompany.local.
    5. Click to select the internal domain address, and then click Set as
    Primary.
    6. Click to select the POP3 domain address, and then click Edit.
    7. Clear the box that says This Exchange Organization is responsible for
    all mail delivery to this address, and then click OK.
    8. Click OK to apply the changes.
    9. Click Yes or OK two times to update all corresponding recipient e-mail
    addresses.
    10. Right-click Recipient Policies in the left pane, point to New, and
    then click Recipient Policy.

    Note If you have Exchange Server 2000 Service Pack 1 (SP1) or later, a
    dialog box appears that prompts you to select the type of recipient policy
    that you want to create. In this case, click to select the E-Mail Addresses
    check box, and then click OK.
    11. Type a name for the recipient policy, and then click Modify.
    12. In the Find Exchange Recipients dialog box, click to select Users with
    Exchange mailbox, and clear all the other check boxes.
    13. Click OK, and then click OK on the warning message that you receive.
    14. Click the E-Mail Addresses tab.
    15. Click to select the POP3 domain address, and then click Set as
    Primary.
    16. Click OK to apply the changes.
    17. Click Yes or OK two times to update all corresponding recipient e-mail
    addresses.
    Note Every time that you run the Internet Connection Wizard or the
    Configure E-mail and Internet Connection Wizard and set it to modify the
    Exchange settings, the wizard will set the e-mail domain address that you
    enter in the wizard as the primary address on each recipient policy. After
    the wizard is completed, you must repeat the steps that are mentioned in
    this article to modify the recipient policy.
