adding OAuth

[russellbell at gmail.com]

	I relay my mail through gmail.  sendmail uses cyrus sasl to
authenticate.  gmail uses OAuth authentication.  If I could add OAuth
to cyrus I could disable gmail requiring that I 'allow less secure
apps'.  I think the authentication I use for my own messages is good
enough; I worry about the vulnerability to which 'allow less secure
apps' exposes my account from attack by others.  

	gmail put both messages from this mailing list in my spam
folder.
