Hi,

could you add webmail.disroot.org to authorized domains ?

We followed your guidelines here https://github.com/mailvelope/mailvelope/wiki/Guidelines-for-email-providers:

• It works without issues.
• 'Mention on your website': see here https://disroot.org/en/services/email
• "Provide a documentation how to use Mailvelope with your application...": see here https://howto.disroot.org/en/tutorials/email/webmail/roundcube/encryption

thanks a lot
