Hello

I try to login from Roundcube to Dovecot IMAP and I get the following error message:

Jun  1 14:05:59 chogolisa roundcube: IMAP Error: Login failed for zahn from 84.253.50.193. Empty startup greeting (chogolisa.akadia.com:993) in /usr/local/roundcubemail-1.0.12/program/lib/Roundcube/rcube_imap.php on line 184 (POST /?_task=login?_task=login&_action=login)

My configuration in config.inc.php for IMAP is as follows:

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

I can login without any problems with TLS from Thunderbird and any mobilphone!

So I think it's a roundcube Problem.

I can also send Mails from Roundcube to the Postfix Mailserver, without any Problems.

$config['smtp_server'] = 'tls://chogolisa.akadia.com'; $config['smtp_port'] = 587;

Can you help me for the "Empty startup greeting" message error. I googeld the whole internet without finding a solution - Thanks!
