Hello

I try to connect to dovecot from roundcube using this setup:

$config['default_host'] = 'ssl://chogolisa.akadia.com'; $config['default_port'] = 993;

and I get the following error message from dovecot:

Jun 19 11:30:21 chogolisa dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=84.253.50.195, lip=84.253.50.195, TLS handshaking: Connection closed, session=

When I try to connect from:

$config['default_host'] = 'tls://chogolisa.akadia.com'; $config['default_port'] = 143;

it works !

Roundcube: 1.0.12 Dovecot: 2.3.6

Can you help me ?

Look like your using a very old roundcube instance. Maybe you should start by updating it. I'm using the same setting with roundcube 1.3.9 (ssl://hostname ssl://hostname, port 993), and never had any issue connection dovecot.
