Event 1070 is logged and e-mail messages are not delivered with the SBS 2003 Connector for POP3 Mailboxes (842293)

RESOLUTION

To work around this issue, add the POP3 e-mail address as a secondary SMTP address in the Exchange default recipient policy, and then restart the Internet Information Service (IIS). To do this, follow these steps.

Add a secondary SMTP address to the Exchange recipient policy

1. Click Start, point to All Programs, point to Microsoft Exchange, and then click System Manager.
2. Expand Recipients, and then click Recipient Policies.
3. In the right pane, right-click the Default Policy, and then click Properties.
4. Click the E-Mail Addresses (Policy) tab.
5. Verify that the local domain name appears in the SMTP address and that you do not have an SMTP address configured for an external domain, such as an ISP's domain name.
6. Click New, click SMTP Address, and then click OK.
7. Type the POP3 e-mail address, such as @MyISP.com
8. Click to clear This Exchange Organization is responsible for all mail delivery to this address.
9. Click OK.
10. Click to check the SMTP address you created in step 9.
    
    Note Do not click Set as Primary.
11. Click OK, click Yes, and then click Yes.
12. Quit Exchange System Manager.

Restart the IIS service

1. Click Start, click Run, and then type cmd.
2. At the command prompt type iisreset, and then press ENTER.

Configure the primary e-mail address for the POP3 users

The primary e-mail address in Exchange is the address that appears on the From line when a user sends an e-mail message. Some users may want their primary e-mail address in Exchange to match their POP3 e-mail address. To configure the primary e-mail address in Exchange to match the POP3 e-mail address, use one of the following procedures, depending on whether you want to configure the user accounts individually, or you want to configure a group of user accounts at the same time. This step is optional.

Method 1: Configure the user accounts individually

If only a few users want their primary e-mail address to match their POP3 e-mail address, you can change these user accounts individually. To change the user accounts individually, follow these steps:

1. Click Start, click All Programs, click Administrative Tools, and then click Active Directory Users and Computers.
2. Expand the container where the user accounts are located, right-click the user who you want, and then click Properties.
3. Click the E-mail Addresses tab, and then click to clear Automatically update e-mail addresses based on recipient policy.
4. Click the POP3 e-mail address, click Set as Primary, and then click OK.
5. Quit Active Directory Users and Computers.

Method 2: Configure a group of user accounts at the same time

If several users want their primary e-mail address in Exchange to match their POP3 e-mail address, you can change a group of user accounts at the same time. To change a group of user accounts at the same time, follow these steps:

1. Click Start, point to All Programs, point to Microsoft Exchange, and then click System Manager.
2. Expand Recipients.
3. Right-click Recipient Policies, point to New, and then click Recipient Policy.
4. Click to select E-Mail Addresses, and then click OK.
5. In the Name box, type a name for the new recipient policy. For example, type POP3 Users.
6. Click Modify.
7. In the Find Exchange Recipients box, click to select Users with Exchange mailbox, and clear all the other check boxes.
8. Click Find Now.
9. While pressing the Ctrl key, click to select the user accounts in the Search results box, and then click OK.
10. Click OK on the warning message about recipient policy filter changes.
11. Click the E-Mail Addresses (Policy) tab.
12. Click the POP3 e-mail address, and then click Set as Primary. Do not clear the check box for this address.
13. Click OK, and then click Yes two times to update the e-mail addresses.
