Symptom

You do not receive email notifications, and see something like the following error messages when setting up email in the cloud failover appliance (CFA) Management Console › Settings:

Could not sent e-mail notifications, please check settings: Could not connect to SNTP host: 10.0.0.6 port 25, nested exception is java.net.ConnectException: Connection timed out.
Can not send email notifications, please check settings: Invalid Addresses; nested exception is: javax.mail.SendFailedException: 550 rejecting spoofed message
Could not connect to SMTP host: relay.ufa-slco.org, port: 25

Steps to resolve

Often these errors are related to settings on the email server in use. Rather than using a separate email server, try using localhost in the Email Server box, leaving the Username and Password boxes empty.

By default, the CFA will use localhost to send email messages directly from the CFA.

To troubleshoot and diagnose the errors while still using your own email server, try the following:

  1. In the CFA Management Console, go to the Support tab.

  2. Ping the IP address of the email server you are using.

  3. If pinging fails, try to trace route to the same IP to determine where the disconnect occurs.

  4. Check and reset the relay policies on the SMTP server.

  5. If possible, reboot that server or restart those services.

  6. Add another email address in the Email To box that uses a different email server than the one currently in use.
