Roundcube default config and postupcp file

[Cistech]

Hi,
After looking for this old thread:
Roundcube, default config for "identities access level"

I've found what I was looking for.
I'm using 11.58 and going to 11.60 version, but I see default "identities access level" on Roundcube is 0:
$config['identities_level'] = 0;

This would allow enduser to setup any email address in their identities and possible cause spam, so please take a look to change it by installation default as security issue.

I was looking for postupcp file, but I only find information for 11.32 version. I don't if this file is working yet and how syntax would be.
I want to do these changes as permanent to new accounts defaults, on /usr/local/cpanel/base/3rdparty/roundcube/config/config.inc.php file
$config['identities_level'] = 1;
$config['language'] = es_AR; (or es_ES)

How can I do that?

Thanks in advance

Hello,

Have you considered enabling the "EXPERIMENTAL: Rewrite From: header to match actual sender" option under the "Mail" tab in "WHM >> Tweak Settings"? Per it's description:

If you enabled this option, the From: header will be rewritten to be the email address of the actual message sender. If you choose the "remote" option, only messages that are being sent to remote destinations will be affected.

Thank you.
