Roundcube - Connection to storage server failed.

After creating the email accounts. I went to www.mydomain.com/roundcube

after entering the information, I am getting this error " Connection to storage server failed."

have you tried ot tail/check mailserver log ?

how do i do that? also I found that "dovecot is stopped" I clicked on start, it doesn't work.

than that is your issue, is this a new server installation or ?

It would be the best that you contact support
http://centos-webpanel.com/contact

yes, it is a new installation.

service dovecot start and let us know what error it throws.

I have the same issue, when I try to login I am getting this error: "connection to storage server failed." This is happening in a new installation using CWP WebPanel.

[root@home ~]# service dovecot restart
Stopping Dovecot Imap:                                    [  OK  ]
Starting Dovecot Imap:                                     [  OK  ]
[root@home ~]#

Any ideas on how to solve this?

This is how you fix it:

Check the log:
tail /var/log/dovecot.log


if you see : Fatal: Unknown database driver 'mysql'
Meaning missing package! Dovecot requires the dovecot-mysql package to run mysql authentication. This problem is simply cured by installing it with yum:

yum install dovecot-mysql

Thank you!!
