Custom Roundcube Plugin for Whitelisting Email Senders

We have hundreds of customers that don’t have access to cPanel and wouldn’t know what to do with it if they did!

We need a way for the end user to be able to trust senders and add them to a whitelist, without cPanel access.

In my ticket with Liam at Brixly, he said they could potentially make a custom Roundcube plugin to allow this functionality.
