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,

Any response for this?
Re: IMAP STARTTLS and SSL/TLS
You don't understand how STARTTLS (or TLS in general) works, it's used to "turn" an unsecure connection channel into a secure one after the connection is established. A SSL/TLS socket performs the TLS handshaking and secures the channel on connection establishment so there's no need of the STARTTLS roundtrip as that was already done at the beginning of the said connection.sindrehi wrote: ↑Wed Nov 13, 2019 8:27 amHi,
