[Users] aol / verizon oauth2 again

[David Fletcher]

Hi Amadeus,

In the short term you're probably out of luck unless you're interested
to get into patching and recompiling Claws Mail.

The services provided by Yahoo, AOL and Verizon appear to be based on
pretty much identical technology but with different URLs for the
authentication servers. Currently Yahoo is available in Claws
(api.login.yahoo.com - this is for the OAUTH2 process internally, it's
not the IMAP server address that you configure yourself). Working with
AOL and Verizon might be as simple as changing this to api.login.aol.com
or api.login.verizon.com within the source code but that's totally
untested. A more user configurable version is a potential for the future
but doesn't exist now.

Even if that works you'd need to register a ClientID with them. The
developer documentation for all three of these email providers is
something they require forms filling just for permission to read it!
https://developer.yahooinc.com/mail/documentation
https://developer.yahooinc.com/mail/developer-access-mail-form

Sorting out OAUTH2 for Google and Microsoft had similar difficulties but
at least all their documentation is public. The actual work required
probably isn't that great, but it needs someone that wants it enough to
push forward with understanding how to configure it.

Short answer - you're out of luck. It's a long shot but you could try
setting it on Yahoo and see what happens (but it would still need a
clientID entering).

Best regards, David.
