PURPOSE
Add some improvements in mail gateway: remove private discussion, improve
bounce management, allow resetting bounce counters, improve automatic set or
reset of blacklists and ease mass mailing inheritance.
SPECIFICATIONS
Purpose
* move bounce information detection in message parsing. It allows to have
this information available in various steps of routing instead of having
to manually re-compute them;
* handle bounce in specific methods allowing easy override;
* improve bounce management, notably when detecting a bounce not linked
to the bounce alias configuration;
* better integration with blacklist mechanism;
Specifications
* compute bounce information in ``_message_parse_extract_bounce``.It parses
bounce information and returns a dictionary allowing to update parsed email
values;
* remove override in mass_mailign that basically does what mail already
does;
* manage bounce in ``_routing_handle_bounce``;
* when detecting a bounce, correctly call the bounce management method on
all models inheriting from blacklist;
* correctly update bounce counter;
* bounced mailing traces and automatic blacklist in mass mailing should
be done in ``_routing_handle_bounce``;
* add some tests;
