Answer 1

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 2

It means dovecot is not running.

run sudo dovecot

this was the solution I got after spending hours in frustration

Answer 3

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([e-mail]): Error: user [e-mail]: 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 4

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

Answer 5

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 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.
