Answer 1

I had this issue when upgrading from Debian Jessie to Stretch. I looked in the log:

/var/log/syslog

and found that the problem was that I was disabling protocol SSLv2 explicitly, and it was not supported anymore. I removed it from the list of protocols and everything worked fine.

Answer 2

I had the same problem after migrating to a new server, I thorough check of the config show that my IMAP and IMAPS were disabled, I simply enabled both service and restart the server.

Answer 3

Try turning all the debugging options on and talk to the IMAP server directly without involving RoundCube, see this guide. That way you can be sure that your IMAP server is working before trying to get RoundCube working.

Answer 4

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

Answer 5

I had same problem recently after successful installation of roundcube

first I tried these two command lines:

netstat -tulpn | grep :143

telnet localhost 143

I got connection refused error messages.

so I have to install telnet

apt-get install telnetd

After installation successful then run Restarts

/etc/init.d/openbsd-inetd restart

/etc/init.d/dovecot restart

Then again run

 netstat -tulpn | grep :143

Result

tcp        0      0 0.0.0.0:143             0.0.0.0:*               LISTEN      13439/dovecot
tcp6       0      0 :::143                  :::*                    LISTEN      13439/dovecot

Try Second test run

telnet localhost 143

Result

Trying 127.0.0.1...

Answer 6

One possible cause is that your Dovecot installation is not working. This happened to me after changing mysql version. I had to do:

sudo apt-get install dovecot-mysql
sudo service dovecot restart

Then it worked.
