This Plugin makes Roundcube webmail show the encrypted part of pgp/mime-formatted messages as text/plain.

Tools like Mailvelope can handle multiparted messages fine, but only if they can get their hands on it.

To customize the text that prefixes the displayed message-part see localization/


Confirmed to be working with Roundcube v1.0.x and v1.1.x.


To use the plugin drop the code into Roundcube's plugins-folder and enable it in Roundcube's config. E.g.:

cd $roundcube/plugins
git clone git://
vim ../config/

The feature will be enabled for all users if the plugin is activated. You can control the default by setting the following option in Roundcube config:

// display of encrypted pgp/mime content in mail view
$config['show_pgp_mime'] = false;
