SUMMARY

This document outlines issues and gives direction on how to troubleshoot and resolve authentication problems.

DETAIL

1. Using the MailEnable Administration Program, open the Properties of the SMTP Connector and select the SMTP tab properties. Click on the Access Control Button and ensure that the option to "Grant Access" is selected.

2. Using the MailEnable Administration Program, open the Properties of the SMTP Connector and select the relay tab.  Ensure that "Allow Relay for Authenticated Users" is selected.

3. On the same Properties page click the Authentication Method and ensure it is set to MailEnable/Integrated Authentication

4. Using the MailEnable Administration Program, open the Properties of the POP Service and select the POP tab.

Select the Access Control Button and ensure that the option to Grant Access is selected.

Mail Client Testing and Diagnosis

1. Configure the mail client to access the MailEnable server. Ensure that the mail client has not been configured to use Secure Password Authentication or to use SSL when connecting to MailEnable Services. Also ensure that the usernames specified for authenticating are in the format of MAILBOX@POSTOFFICE

2. Attempt to connect to MailEnable using the mail client.

3. Open the MailEnable POP and SMTP Activity log files using the MailEnable Administration Program and verify that the connection attempt is being made to the server.

4. Inspect the respective Debug Log Files at the time of connection to determine if there are any errors in the log files. (If there is nothing in the log files then either the mail client settings are invalid or a firewall or network connectivity failure is preventing access to the server.)

5. Any error codes returned or noted by the mail client should be verified against the vendor's knowledge base or documentation.
