[Mailman-Developers] Dropping Persona

[Simon Hanna]

> I just found another solution: django-allauth
> http://www.intenct.nl/projects/django-allauth/
> http://django-allauth.readthedocs.org/en/latest/overview.html
> https://github.com/pennersr/django-allauth
> 
> It's a relatively large project. It has 2000+ stars and about 800 forks on github. The other two I
> introduced can't get these values when adding them together.
> 
> About their functionalit quoting from their docs:
> * Signup of both local and social accounts
> * Connecting more than one social account to a local account
> * Disconnecting a social account – requires setting a password if only the local account remains
> * Optional instant-signup for social accounts – no questions asked
> * E-mail address management (multiple e-mail addresses, setting a primary)
> * Password forgotten flow
> * E-mail address verification flow
> 
> They are basically supporting every OAuth provider out there
> 
> They have more signals than the other two projects I introduced. Some of them are:
> * when a user signs up
> * when a user adds an email
> * when the user removes an email
> 
> I didn't look at the code yet but I think they are only using emails and not usernames.

I just opened a merge request over at postorius
https://gitlab.com/mailman/postorius/merge_requests/91

It includes basic functionality for django-allauth. All the included code should work, the merge
request contains info about what still needs to be done. What do you think?
