We remove 'secret' field, as it won't be of use in interactions
between la Régie and dimail. Régie credentials will be stored and used
as project variable.
dimail is called twice when creating a mailbox (once for the token,
and once for the post on mailbox endpoint). we want to clarify
the status_codes and messages of each error to inform user and ease debug
Latest dimail modification lead to a bug in our app, preventing mailbox creation
from working properly. I swapped old dimail url to new one, mirrored dimail
modification and fixed tests and tada!
- manage 403 returned by dimail API when mail domain secret is not valid
- improve some tests
- improve MailboxFactory to mock success for dimail API POST call
- override 403.html to return a nice failing error in django admin
- an error message is displayed on mailbox creation form of frontend
We want people to create new mailboxes in La Régie.
This commit adds integration with intermediary dimail-api,
which will in turn send our email creation request to Open-Xchange.
