Answer 1

It means dovecot is not running.
run sudo dovecot
this was the solution I got after spending hours in frustration

Answer 2

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 3

edit 15-mailboxes.conf by running
nano /etc/dovecot/conf.d/15-mailboxes.conf
add following text inside namespace inbox {} block:
namespace inbox {
inbox = yes
...
save the file and run:
service dovecot restart
and you are done..!

Answer 4

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.

Answer 5

I was able to solve this issue by referring to Dovecot Status.
First of all, make sure you don't use an incognito browser window, then Check Dovecot Status by running this command
service dovecot status
it will show you that:
● dovecot.service - Dovecot IMAP/POP3 email server
Loaded: loaded (/lib/systemd/system/dovecot.service; enabled; vendor preset: enabled)
Active: **inactive** (dead) since Mon 2020-03-30 21:03:32 UTC; 29min ago
Docs: man:dovecot(1)
http://wiki2.dovecot.org/
Main PID: 910 (code=exited, status=0/SUCCESS)
Then run service dovecot start

Answer 6

Some Devcot config files had been corrupted. So you need to fix by recreate new config file and remove existing one. Login to root by SSH through putty software
Execute these 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
Now you can Login into your webmail app. No error will appear.

Answer 7

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 8

remove below file and login.
/etc/dovecot/conf.d/15-mailboxes.conf
or use
sudo rm -rf nano /etc/dovecot/conf.d/15-mailboxes.conf

Answer 9

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 10

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 11

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...
Connected to localhost.

Answer 12

I had faced same issue and I found solution by following.
I had checked log by following command.
tail /var/log/dovecot.log
By using above command , I found following error in log.
Sep 01 10:39:50 imap(mail#yourdomain.com): Error: user
mail#yourdomain.com: Initialization failed: Initializing mail storage
from mail_location setting failed:
mkdir(/var/vmail/yourdomain.com/mail) failed: Permission denied
(euid=101(vmail) egid=12(mail) missing +w perm: /var/vmail, dir owned
by 4325:4319 mode=0751)
so I noticed that server is unable to create the directory with name "yourdomain.com" and it require "+w" permission. I have also noticed that "yourdomain.com" directory requires ownership "vmail:mail".
Finally, Directory had been created using following command .
cd /var/vmail/;
mkdir yourdomain.com;
chown vmail:mail yourdomain.com -R;
chmod +w yourdomain.com;
That's it.
I hope this answer might help you.

Answer 13

I had a similar issue when setting up iRedMail dockerized version on Ubuntu 20.04.
The issue was that Dovecot was not running in the container when I checked using the command - service dovecot status. And when I tried starting the service using the command - service dovecot start I got the error
root#mail:/var/spool/postfix# service dovecot start
* Starting IMAP/POP3 mail server dovecot
Error: bind(/var/spool/postfix/private/dovecot-auth) failed: No such file or directory
Fatal: Failed to start listeners
I also ran the command below to confirm that my dovecot configuration was fine:
dovecot -n
And yes the output from the command showed that it was fine.
Here's how I fixed it:
The issue was caused by Postfix not being installed/running on the in my container which I discovered when I checked the docker logs for the container using - docker logs container-id. The file /var/spool/postfix/private/dovecot-auth which Dovecot was referencing was supposed to be created by Postfix, however, since the script to install Postfix failed because the correct path to the script was not picked when building the iRedMail image, this issue then came up as Dovecot could not find the file /var/spool/postfix/private/dovecot-auth:
[iRedMail] [Entrypoint] /docker/entrypoints/postfix.sh
/docker/entrypoints/functions.sh: line 113: /docker/entrypoints/postfix.sh: No such file or directory
[iRedMail] [Entrypoint] /docker/entrypoints/mlmmj.sh
[iRedMail] [Entrypoint] /docker/entrypoints/mlmmjadmin.sh
[iRedMail] [Entrypoint] /docker/entrypoints/iredapd.sh
[iRedMail] [Entrypoint] /docker/entrypoints/antispam.sh
mail: cannot send message: Process exited with a non-zero status
All I had to do was to pull the docker repository for iRedMail using git clone -b stable https://github.com/iredmail/dockerized, rebuilt the image in my local using docker build . --tag iredmail:latest -f dockerized/Dockerfiles/Dockerfile, and then run it. This time the correct location of my Postfix install script was picked, and the Postfix installation and setup ran fine.
And when I checked Dovecot service again using:
service dovecot start
It showed me that it was running fine.
That's all

Answer 14

You should remove to dovecot mail server and Use another mail services, Two services could be conflitcs therefore You must remove a mail services, I've tried to this error for 2 days.
CODE : yum remove dovecot
If you had used this code Dovecot would have remove from your server and There is not conflitcs
