Bug#1006888: RFP: sasl-xoauth2 -- XOAUTH2 plugin for libsasl2

[Etienne Dechamps <etienne@edechamps.fr>]

I would like to second this RFP. I recently received a notification
from Google warning me that they are phasing out password
authentication, which (in the case of my account) will stop working on
May 30. Once that happens, OAuth2 will be the only supported GMail
SMTP authentication mechanism. This in turn means sasl-xoauth2 (or
equivalent) will become a hard requirement to be able to use GMail
SMTP from Postfix, for example.
