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
The number of message bounce is incremented each time the email bounce
on a specific email address. To have a correct information, we should
reset to zero this counter if we receive a mail from this address.
Indeed, if we receive an email from an email address, this email is
active and the message bounce number (if > 0) is not relevant anymore.
Only models inheriting form blacklist are impacted by this improvement
in order to limit a bit side effect.
Also, add a check in autoblacklist rule. No need to check the stats
if message_bounce is < 5.
This commit introduces
* ``_routing_reset_bounce`` routing method managing the bounce reset;
* ``_message_reset_bounce`` model method that resets bounce counter
in blacklist enabled models;
