Description
Custom OAuth provider support for utilizing 2 factor auth for email login. This should be something every client should have but no one has done this yet and for security focused organizations, getting 2 factor email is a requirement especially in the government space.
Every cloud provider has this for their own OAuth but having a interface to add your own would revolutionize on-prem email making it just as secure as the cloud providers with having control over your data. IMAP servers like Dovecot already support using OAuth but no client on the market or I have found supports adding custom providers.
Is this a planned feature and if so, what is the timeline. I would like to help anyway possible. I have seen this on #52 and found a way by hard-coded my provider but making this simpler would be preferred
