Resolved MU killed severals services and license checks

[Tanktiger]

Hello,
we have done a Plesk MU on our Plesk Ony 17.8.11. At first the phpmyadmin was not reachable and we cant access the mail settings with the UI. Ive tried to repari mail wit plesk repair mail but with no luck.
Then i tried with /usr/local/psa/admin/sbin/mchk --with-spam but again no luck. The problem is that there is no user in the auth_db file from dovecot.

Here some logs:
==> Checking for: mailsrv_conf_init... ok
==> Checking for: mail_handlers_init... ok
==> Checking for: mailsrv_entities_dump... /usr/local/psa/admin/sbin/mchk --with-spam

Errors occured in mail restore procedure

/usr/lib/plesk-9.0/remote_mail_restore/mail_transport_restore

We do nightly backups but it has 42gb and i cant backup with Plesk UI because i have no rights to this says Plesk. Im logged in with the admin.

Here is some logs from maillog:
Oct 5 11:28:17 XXXX dovecot_authdb_plesk[4019]: No such user '[email protected]' in mail authorization database
Oct 5 11:28:20 XXXX dovecot_authdb_plesk[4019]: No such user '[email protected]' in mail authorization database

Postfix and Dovecot are running - i can see them and restart the service without a problem

Can someone help me what to do?

In fact, we have not recommended using mchk utility for a long time. If you need to fix mailserver settings, please use

# plesk repair mail

command. Also following KB article may be useful for you Email cannot be delivered: No such user in mail authorization database

Thanks for your fast answer,

This commands shows the same message like mchk
plesk repair mail

Error messages: 0; Warnings: 0; Errors resolved: 0

Ive resolved the issue after multiple tests.

I wanted to reinstall postfix but got error that mysql could not be stopped. I cant stopped mysql because the system has a lot requests, so this must be planned.

1. So we created an Backup with Plesk.
2. Login with SSH and root on our server
3. shutdown mysql service (service mysql stop)
4. remove dovecot and postfix
# plesk installer remove --components dovecot postfix
5. start mysql service
6. add dovecot and postfix
# plesk installer add --components dovecot postfix
7. Everything worked like before!

@Hint: no emails on the server were deleted
