Back in 2012, I published an Android email client, ChiaraMail for Android, that was based on an Open Source mail client called K-9 Mail and made use of AWS. It ran well but cost me a fortune in AWS fees,so I shut the service down in 2015. Also, the app required users to log in with their email address and password, since it needed both to connect to the IMAP and SMTP servers for receiving and sending mail, and this became a problem when Google began standardizing on OAUTH2.
Now I'm thinking of rewriting the app using Firebase for email authentication. My question is, can I somehow use the Firebase authentication token to connect to the IMAP and SMTP servers? If not, is there any Firebase mechanism that will help me rebuild my email client?
