Emails are not Being Received by Administrators and Users

Problem    Emails are not being received by administrators and users.

Possible Cause    Your SMTP hostname might be incorrectly configured.

Possible Cause    Your SMTP server might be down.

Possible Cause    SMTP server email requests might be blocked.

Solution    Make sure your SMTP hostname is correctly configured. If it is not configured correct, put your system in maintenance mode and correct the SMTP information, save your changes and turn off maintenance mode. After your system restarts, the status should be UP. Refer to "Configuring an SMTP Server" in the Administration Guide for more information.

Solution    Check your logs to determine if SMTP server email requests are being blocked. Fix your SMTP server issue or specify a different SMTP server.

Solution    You can test email by selecting Users > Email Users and then sending an email to a host.

SMTP Email Server Issues on a System with TLS-Based Authentication

Problem    My SMTP email server is not working.

Possible Cause    TLS is enabled and your self-signed certificate is not accepted as valid by your system.

Solution    This is a known limitation. You cannot configure your mail server to use a self-signed certificate with TLS enabled.

Email with Reports not Received

Problem    An administrator selects Customize Reports to request system logs, but the administrator does not receive email notification after the logs are collected

Possible Cause    The NTP server may be down or unreachable.

Solution    Make sure that there is an NTP server configured properly on the ESXI hosts of your Cisco WebEx Meetings Server with your virtual machines. Verify that the NTP server is operational and reachable. If your NTP server is operational, contact Cisco Technical Assistance Center (TAC) for further assistance.
