# Which Problems Are Solved

- Some mail providers (e.g.: MS Exchange) have deprecated plain auth

# How the Problems Are Solved

Adds XOauth2 auth option to SMPT
- SMTP config now can contain XOAuth2 auth config
- Proto files are updated to have a oneof for configuration selection.

a breaking change. These can be removed in the future.
- Columns are added to the database to persist the config
