Rainloop-webmail: How do you install custom plugins?

[mzummo]

How can custom plugins be installed (i have modified the change password plugin but I do not see any apparent way to install the plugin)

[mzummo]

found the answer:

plugins can be installed manually via the following directory:

HTML_ROOT /rainloop/data/_data_/_default_/plugins

I'm trying to install this plugin: https://github.com/RainLoop/rainloop-webmail/blob/master/plugins/override-smtp-credentials/index.php

I copied that file into _HTML_ROOT /rainloop/data/data/default/plugins_ as described above. But I don't see any changes in the SMTP interface. The plugin is supposed to allow you to override SMTP login credentials.

Am I installing the plugin wrong? There is very little documentation on it.

Thank you.
