Starting at 2022-06-01 Google requires either an application password or
OAuth2 for logging in.  Check the Gentoo archives for a thread with sub-
ject `Google and "fetchmail" + "ssmtp"´ started by me at 2022-03-17.

This thread refers  to an article  on the Web  describing how to support
OAuth2 for Fetchmail and Postfix and also contains a detailed descripti-
on of my personal solution using OAuth2 with neither Fetchmail nor Post-
fix, which still works.

Sincerely,
  Rainer
