Since sending e-mails requires some significant prerequisites, would it be possible to add a feature to send notifications to a Telegram bot instead (while keeping both features) of sending e-mail notifications?
Well, we live in an opensource world, nobody is stopping you from developing it your self, create a PR and see if it gets merged.
I think we have other developing items laying which could have attention instead of adding a different e-mail interface which transfers it to telegram instead.
Telegram notifications would be nice to have, but compared to email, I don’t think any chat platform is universal enough to merit specific support in bitwarden_rs, especially considering there are not many people actively contributing code to the project.
A more generic solution like webhooks would probably make more sense for bitwarden_rs. That would make it possible to pass events to some other program (e.g., a bot server) that can ingest the webhook payload and take an appropriate action (e.g., have the bot send a message).
