Roundcube unresponsible when using ssl/tls without tls:// prefix

[Jan-Tristan Kruse]

When I try to connect to an IMAP-Server via SSL/TLS on Port 993 and do not enter the Hostname with tls:// prefix (i.e. imap.example.com instead of tls://imap.example.com) the whole Roundcube gets unresponsive for this session when I try to switch to the new identity.

The setting “Secure connection (TLS)” is enabled.

The Log shows the following:

IMAP Error: Login failed for [e-mail] against imap.example.com. Empty startup greeting (imap.example.com:993) in /home/roundcube/program/lib/Roundcube/rcube_imap.php on line 202 (GET /?_task=mail&_mbox=INBOX)

The expected behavior for me would be a hint, that I should use the tls:// prefix, and obviously that I’m still able to change settings.

I’m thankful that this issue got opened. I couldn’t figure out why my IMAP connections were failing, but adding the tls:// prefix fixed it.

Fixed login problem when server requires TLS. Closes #47 Closes #45

Thank you.

Adding ssl:// to the IMAP host name fixed the issue. For others this may be tls://

[Jan-Tristan Kruse]

Sadly, this does not solve the issue. The session still gets unresponsive when using a Port which expects TLS (993) WITHOUT using the TLS-Button in the ident_switch Plugin.

Hi. Port 993 is not for TLS. It’s SSL.

Plugin does not support SSL because it should be changed to TLS years ago.

Glad I spotted this issue. adding ssl:// to my imap url and tls:// to my smtp url fixed the hangs and failures I was experiencing.
