Install mail on a mail server program such as Outlook.

I am trying to connect email with Outlook but it is not working even though I have a VPS server with aapanel panel installed. Can you help me solve the problem?

You can use this command to check whether the correct SSL is configured
openssl s_client -connect mail.135mailtest.com:587 -starttls smtp
or
openssl s_client -connect mail.135mailtest.com:465 -starttls smtp

If the display is not OK, try to save the SSL certificate again, or please re-apply for SSL
