smtpmail with xoauth2

[Vladimir Nikishkin]

Hello, everyone

I wonder if anyone has smtpmail working with an xoauth2 account.

I have managed to make mbsync fetch my mail over IMAP using the
following entry in ~/.mbsyncrc
`PassCmd "~/bin/mutt_oauth2.py ~/tokens/my-mail.tokens"`
(I have already applied for the tokens and such.)
However, I haven't found a way to feed the same command to Emacs's
authsource library. (or smtpmail library).

Can someone help?
