Symptoms

Plesk Premuim Email extension by Kolab is installed and enabled.
The following error is displayed when trying to apply the configuration at Domains > example.com > Apache & nginx page:

Invalid nginx configuration: nginx: [emerg] "server" directive is not allowed here in /etc/nginx/plesk.conf.d/vhosts/example.com.conf:31 nginx: configuration file /etc/nginx/nginx.conf test failed
Unable to use the current nginx configuration file and to rollback to the previous version of the file because they both contain invalid configuration.

Plesk Premuim Email extension provides invalid mail autodiscovery section to templates during building Nginx virtual host configuration files.

This is extension bug with ID PPPM-14026.

Until the bug is fixed, apply the next workaround:

Connect to the server via SSH.
Backup original /opt/psa/admin/plib/Template/Processor.php file:

# cp -a /opt/psa/admin/plib/Template/Processor.php{,.bak}
Download custom fixed file:

# curl -LO https://support.plesk.com/hc/en-us/article_attachments/15329755898519/Processor.php
Replace the original file:

# mv -f ./Processor.php /opt/psa/admin/plib/Template/Processor.php

Connect to the server via SSH.
Backup original /usr/local/psa/admin/plib/Template/Processor.php file:

# cp -a /usr/local/psa/admin/plib/Template/Processor.php{,.bak}
Download custom fixed file:

# curl -LO https://support.plesk.com/hc/en-us/article_attachments/15329755898519/Processor.php
Replace the original file:

# mv -f ./Processor.php /usr/local/psa/admin/plib/Template/Processor.php
