I successfully installed roundcube 0.9.0 (on 1and1 web hosting) and I have been using it for a couple of days now. Suddenly no users can login and it returns a 'Unable to connect to storage server' error, I hadn't changed anything to prompt this. I noticed there was a new version available (0.9.1) so I manually upgraded, I now get a different error 'Connection to IMAP server failed', is this the same issue or a different one?
The log file is reporting this error:
[23-May-2013 02:12:06 +0100]: IMAP Error: Login failed for xxxx@xxxx.co.uk from x.x.x.x. Could not connect to imap.1and1.co.uk:143: Connection refused in .../webmail/roundcubemail-0.9.1/program/lib/Roundcube/rcube_imap.php on line 184 (POST /?_task=login&_action=login)
I can confirm that the imap server is working fine when accessed via other mail software (eg. outlook). I can't think what could've caused this issue or how I can go about fixing it, is anybody able to point me in the right direction?
