I am using Manager 19.2.90 and unable to send emails using smtp via my VPS running cpanel.
When I test the email settings I get no error messages and no email is received.
I am using my domain with autossl cpanel certificate, port 587 (configured for exim and csf firewall are open) with SSL enabled. I can set you up with a temporary email account on the server if you need it for testing.
If there are specific tests I can run, please advice.
I have gone through the previous posts and nothing there seems to solve the problem. They also predate using autossl certificates either from cpanel or letsencrypt.
I am using the builtin mail server for now, but because my VPS server has DKIM and SPF settings, they can be rejected as spam.
