Effective October 3, 2022, use of nmh's Google OAuth mechanism will (or might) be blocked by Google. This feature was introduced in nmh 1.7 to allow receiving and sending through a user's Gmail account.
If you use nmh's mhlogin(1) to login to Gmail, then you use nmh's Google OAuth mechanism. Please let me know if you use it. Alternatives include updating nmh per the Google recommendations, or (I think) using Google APIs. If you use nmh's glogin.py, you're using Google APIs. Details from Google are available here: https://developers.googleblog.com/2022/02/making-oauth-flows-safer.html The "might" and "I think" are due to me not understanding some of Google's announcement. For example, I expected to see a "user-facing warning message" starting September 5, but I don't see any such message. I'm also not sure if glogin.py is affected. It doesn't display any warning message, either. Google has not notified me about it; they did notify me about the older nmh Google OAuth mechanism. Thanks, David
