Gnus, Oauth2, & nnimap-authenticator

[David Masterson]

Does anyone have more documentation on setting up OAuth2 and using it
with NNIMAP in Gnus?  New email systems seem to be moving to Oauth2
protocol, but there is very little documentation on how to set it up
(especially for newbies) with Emacs email packages.  Any hints??

The best way, if you require pure OAuth2, seems to be to hand off to msmtp rather than sending directly from Gnus, although that may trigger significant changes to your Gnus setup.  There is good online material showing how msmtp works with OAuth2.

Of course if your mail system allows for app passwords (you may have to hunt around as the option is often not easy to find) that is easiest, and it's what I do.  I haven't found a major provider that doesn't support app passwords (your mileage may vary).

Hmm. msmtp would handle sending email, correct?  Does it also handle
getting the email from IMAP?

Outlook.com was working fine, but seems to have moved to "Modern
Authentication" (which I think has to do with Oauth2).  So I tried a
free email account on Zohomail, but it has a strict DMARC policy which
causes gnu.org to reject it's email, but Zohomail does accept email from
gnu.org.  I've gotten SMTP working via icloud.com, so I'm using Zohomail
for incoming and Icloud for outgoing.  I'm still not sure of expiring
emails on Gnus and Zohomail (which will eventually overload the space if
expiry doesn't work), so I'm looking at other options.

If you are trying to work with Outlook, davmail
(https://davmail.sourceforge.net/) works well as an intermediary between
gnus and Outlook.

I tried, but I had trouble figuring out Davmail -- the docs are
confusing for a newbie.  Do you have a simplified Davmail properties
file for Gnus<->Outlook you could share along with the Gnus & SMTP setup
in Emacs?  I work better copying from others. ;)

Thanks

When you use Davmail with Gnus then Davmail handles OAuth but not Gnus.
You simply use your user with password and username like you always do.
