Disable altered RPM check for some Rouncube files?

Hello @Gino Viroli,

Technically, you could set the cpanel-roundcubemail RPM to unmanaged using the instructions in the following document:

How to Set or Unset RPM Management - cPanel Knowledge Base - cPanel Documentation

However, doing this means the RPM is no longer managed through cPanel & WHM and would require manual upgrades and maintenance.

Since you can't exclude specific files from the RPM verification check, the better approach is to setup a custom script or command that modifies the files with your preferred changes, and then setup a post stage upcp hook that automatically runs that script/command each time cPanel updates. Information on how to setup a hook to run after cPanel updates (upcp) is available at:

Guide to Standardized Hooks - Software Development Kit - cPanel Documentation
Guide to Standardized Hooks - System Functions - Software Development Kit - cPanel Documentation

Note you'd also need to create an email filter for that specific RPM notification based on it's message body so the system discards the message.

Additionally, I recommend opening a feature request for the ability to customize Roundcube without directly modifying it's configuration files:

Let me know if you have any questions.

Thanks!
