[MlMt] Adding Oauth2 accounts?

[Steven M. Bellovin]

I recently had to add an email account that uses Oauth2 and Duosec. The 
organization has its own domain, but has outsourced its email service to 
Google. As best I can tell, the only way to get an Oauth2 checkbox in 
the "Add an IMAP account" box is to fill in a gmail (or, I guess, 
Outlook) address, which I don't have. Instead, what I did was to add the 
account to Apple Mail and import it. Was there a better way? Could there 
be, e.g., a pull-down menu of Oauth2 "styles" or "providers"? Do I need 
to keep the Apple Mail account alive, if only to renew the token? I'm 
running the Version 2 beta 6119.
