Answer 1

This means dovecot is not working.

run sudo dovecot

That was the solution I got after spending hours in frustration

Answer 2

Try turning on all debugging options and talking directly to the IMAP server without RoundCube, see this guide . This way you can be sure that your IMAP server is working before you try to get RoundCube to work.

Answer 3

edit 15-mailboxes.conf by running

 nano /etc/dovecot/conf.d/15-mailboxes.conf 

add the following text inside the inbox {} block namespace:

 namespace inbox { inbox = yes ... 

save the file and run:

 service dovecot restart 

and you are done ..!

Answer 4

Some Devcot configuration files have been corrupted. Therefore, you need to fix it by creating a new configuration file and deleting the existing one. SSH root login via spatula software

Execute this code

 cd /home /etc/init.d/dovecot stop rm -f */imap/*/*/Maildir/dovecot* rm -f */imap/*/*/Maildir/.*/dovecot* rm -f */Maildir/dovecot* rm -f */Maildir/.*/dovecot* /etc/init.d/dovecot restart 

You can now log in to your webmail application. The error will not appear.

A source

Answer 5

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

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

Then he worked.

Answer 6

delete the file below and login.

 /etc/dovecot/conf.d/15-mailboxes.conf 

or use

 sudo rm -rf nano /etc/dovecot/conf.d/15-mailboxes.conf 

Answer 7

I had the same problem after moving to a new server, I carefully checked the configuration showing that my IMAP and IMAPS were disabled, I just turned on the service and restarted the server.

Answer 8

Here's how you fix it:

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

if you see:

Fatal: Unknown 'mysql' database driver

The value of the 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 9

I had this problem when upgrading from Debian Jessie to Stretch. I looked into the log:

 /var/log/syslog 

and found that the problem was that I disabled SSLv2 explicitly and it was no longer supported. I removed it from the protocol list and everything worked fine.

Answer 10

I had the same issue recently after successfully installing roundcube

First I tried these two command lines:

 netstat -tulpn | grep :143 telnet localhost 143 

I received a connection failure message .

so i have to install telnet

 apt-get install telnetd 

After successful installation, run Restarts

 /etc/init.d/openbsd-inetd restart /etc/init.d/dovecot restart 

Then run again

  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 a second test run

 telnet localhost 143 

Result

 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE START TLS AUTH=PLAIN AUTH=LOGIN] Dovecot (Ubuntu) ready. 

Answer 11

I ran into the same problem and I found a solution by following.

I checked the log for the following command.

 tail /var/log/dovecot.log 

Using the above command, I found the following error in the log.

September 01, 10:39:50 imap ( [e-mail] ): error: user [e-mail] : initialization failed: mail store initialization failed from mail_location parameter: mkdir failed (/var/vmail/yourdomain.com/mail): Denied in access (euid = 101 (vmail) egid = 12 (mail) is missing + w perm: / var / vmail, dir belongs to 4325: mode 4319 = 0751)

therefore, I noticed that the server cannot create a directory with the name "yourdomain.com", and it requires the permission "+ w". I also noticed that the directory "yourdomain.com" requires ownership of "vmail: mail".

Finally, the directory was created using the following command.

 cd /var/vmail/; mkdir yourdomain.com; chown vmail:mail yourdomain.com -R; chmod +w yourdomain.com; 

It.

I hope this answer can help you.

maybe it will help. First configuration on vestacp: Roundcube 'error connecting to the storage server when installing Ubuntu on vestacp for the first time

Answer 13

You must delete the dovecot mail server and use other mail services. Two services can be conflitcs, so you have to delete mail services, I tried this error for 2 days.

CODE: yum remove dovecot

If you used this code, Dovecot would remove from your server and there were no conflitcs
