Email Scheduler Does Not Work

Issue

• Using telnet to connect to port 25 of the email server from the management interface works.
• From the logs we can see that the Palo Alto Networks firewall connects to the email server, but the connection is closed almost immediately.
• Sending a test email using the test email button results in a failure to generate report error.

Workaround

Verify the email server's 220 response, if it is multiple lines then it needs to be set to a single line instead of multiple lines.
