This avoids storing useless "{}" values
in the database when there are no headers,
and avoids having to update all existing
entries when this column is added.
Just requires simple tests before evaluating
the headers contents.
- remove the default footer for mail.group messages,
replace with specific footer with archive and unsubscribe
link
- remove the automatic addition of user signature in
mail.group messages, as many of them will be posted
via the mail gateway and already contain a user signature.
- make it easier to unsubscribe even when not logged in,
as followers who have not signed up will have no
way to login short of signing up.
- remove tests looking for user signature in mail.group posts
- added possibility in mail to have a model adding custom headers in emails sent for notifications for new messages
- mail.group now add list-id and precedence: list in the headers to inform mailing systems that those mails are to be considered as mailing lists
- website_mail_group adds some further data in the headers (subscribe, unsubscribe, archives)
- groups page now display the number of message in the last month
- notification emails are now queued after 50 recipients
