[RCD] New SASL method for SMTP

Hello

I would like to implement a new SASL authentication method for SMTP. It does not seems easy to do with current code, as no plugin hook is there for that.

As I understand, I would need to subclass Net_SMTP and implement a new auth() method. Unfortunately, as the class is written, I would end up duplicating most of the method's code.

I am bound to the conclusion that I have to do a contribution to Net_SMTP first. I suspect it will end up with some kind of sasl_auth_register() rmethod that will allow the inclusion of a new authentication method. Anyone can confirm this is The Best Way?
