Answer

Warning: The content of this article needs to be discussed by a qualified system administrator prior to implementation to prevent service outages caused by misconfiguration.

Note: During a Dovecot upgrade, if the dovecot.local file does not pass the configuration test, the .local file will be renamed to .broken<template>, and a default .local template will be put in its place. Finally, during major upgrades where the main dovecot/main.local is invalid, it forces the dovecotSNI and dovecotSSL templates to also be considered invalid, which will result in them being replaced with a default template to ensure the dovecot service starts.

1. Access your cPanel server via SSH as the 'root' user.

2. Make a copy of the Dovecot main.default file by running the following command:

   # cp -ax /var/cpanel/templates/dovecot/main.default /var/cpanel/templates/dovecot/main.local

3. Modify the configuration using your favorite text editor and add the options you need to change.

4. Rebuild dovecot:

   # /scripts/builddovecotconf 

5. Restart Dovecot:

   # /scripts/restartsrv_dovecot
