8. POP3 Connector Troubleshooting (cont.) POP 3 Connector Evaluate the error message to try to determine the cause of the issue. In this case, the email account I set up for the presentation doesn’t actually exist, so the connector fails to log into the email account at the hosting company. If you cannot determine the problem from here (such as a “transient error”) there is a few other things to try.

9. POP3 Connector Troubleshooting (cont.) Open C:rogram Filesindows Small Business Serverogsop3connectorop3service.log in notepad and scroll to the bottom In our example we had the following error: [t 0] 10/20/09, 04:20:43: EVENT: The credentials provided for user account "test_user+vestalsgap.com" on the server "mail.vestalsgap.com" are incorrect. Verify the user name and password for this user account. What would you do if you had the following error though? See the next slide … [t 0] 10/19/09, 06:25:07: EVENT: Because of transient or unknown failures, one or more messages (1) could not be delivered to 'test_user+vestalsgap.com' on the SMTP server 'localhost'. The messages will be left on the POP3 server. If these failures continue to occur, you can either connect to the POP3 account and retrieve or delete the messages manually, or resolve the problem causing the errors.

10. Web Hosting Email Troubleshooting (cont.) Several things can cause the POP3 Connector from retrieving email: Improper message headers from spammers Attachments size (most common that I’ve seen) Web hosting email account changes, such as username or password. These are easy to identify since the logs should indicate which account has the issue. Simply log into your web hosting provider’s webmail and evaluate the email. Delete spam Download large attachments from webmail and then remove the email In the SBS Console have the POP3 Connector “retrieve now” to verify the problematic email was removed. Web Hosting Email
