I have multiple domains working on my mail server, and all are working normally,
I configured new mail domain "newdomain.ae" normally on mysql mail db, created new user, inbox was created on server,
But when i tried to login to my account on the new mail on round cube, i got the error "login connection to storage server failed"
Round cube's logs were:
[01-Feb-2016 23:00:01 +0200]: IMAP Error: Login failed for myaccount@newdomain.ae from 2.2.2.2. Could not connect to newdomain.ae:143: Connection refused in /var/www/webmail/program/lib/Roundcube/rcube_imap.php on line 184 (POST /mail/?_task=login&_action=login)
Note: the application server is hosted on another different server under domain "newdomain.ae"
