IMAP STARTTLS and SSL/TLS

Post by sindrehi » Wed Nov 13, 2019 8:27 am

Hi,

Is it possible to enable both STARTTLS and SSL/TLS on IMAP?
We have already SSL/TLS working. To enable STARTTLS i found out I had to remove "Require SSL" checkox after listen to alternate port. But then the SSL/TLS option is not working anymore.
From what I understand STARTTLS is more secure than SSL/TLS, so it would be great to be able to offer this option. But if we change setup, then all clients already using SSL/TLS setup will fail.

Best Regards,
Sindre
