When sending the test email of a mass mailing campaign, it might be
observed that the result is different from the final email sent to
customers.
This is because the `body` field of the final mail message is an `Html`
field with options `sanitize_style=True` and `strip_classes=True`. On
the other hand, the `body_html` field the test mail is a simple `Text`
field which is not sanitized.
We sanitize the `body_html` field with similar options.

Since notification emails are not mail templates anymore they do not go
through the mail_template.render_post_process() method that converts
local links to absolute links. This means that buttons and images were
not correctly displayed in notification emails. Indeed those still had
local links.
This commit fixes that by moving the method directly in mail.thread and
calling it accordingly when rendering the notification email. Note that
the method has been changed in order to use regex instead of html
parser. It is done based on work already done in mass mailing application.
Indeed using parsers is complex and time consuming and may create
changes in the html structure that are not intended.
Next step in master is to go through various link modifications in
mass mailing module to see how to handle them properly. Maybe.
The mass-mailing App suffered from severe issues due to its inability
to detect and handle duplicates "at the email level", and the absence
of any global blacklist system, leading to lack of user trust.
Mailing-lists typically include multiple records with the same email,
and it is critical to avoid sending them the same email several times.
A related problem is the unsubscription of an email that is present
in other records (duplicates). Opting out the first email should
automatically blacklist it for other records as well.
Ideally we should have a global blacklist table in order to
share the unsubscription requests globally across models (Leads,
Partners, Mailing-list contacts). It would also allow importing
it from other blacklist systems. (TODO for master)
This commit introduces a partial solution, made of several
small changes:
- In mail.mail: double-check that an outgoing email has the
correct status (`outgoing`) before sending it. This allows
adding emails in the queue and cancelling them before they
actually get sent.
- In crm.lead: force predictable recipients for mass-mailing,
by always using the email of the lead rather than the email
of the linked partner when there is one. This simplifies the
computation of the blacklist and seen list. Other areas in
the codebase already assume as much.
- In mass.mailing:
+ Before sending out a mailing-list batch, compute the
blacklist (all opted-out emails) and the seen_list
(emails who previously received this mail) to make
sure we only ever target valid recipients.
+ While delivering the mass-mailing, any email targeting
an address that is in the blacklist or "seen list" is
canceled before being sent. The corresponding statistics
entry is considered "not delivered".
Also updates the "seen list" continuously.
+ When a mass-mail belongs to a campaign with the
"unique AB/B testing" flag, the "seen list" is
common to the whole campaign, as an extra safety.
+ Auto-delete mass-mailing test messages sent with the
test wizard, to avoid polluting the mail_mail table
Note: this fix uses a simple regex for efficiently extracting
the blacklist in pure SQL from different models, and doing so,
assumes that each record only holds a single email
(no comma-separated adresses). This should be sufficient for
most cases. The regex:
([^ ,;<@]+@[^> ,;]+)
The test wizard will be dropped eventually but it is not possible to delete
the mass-mailing before the transient is cleaned too due to the required field.
To make it faster, add a ondelete cascade on the field.
Closes#15217
When using the "Test Mailing" button, a sample mail was sent to a
particular mail address and a text-like unsubscribe link was added
below the mail body. This link was ugly, ununderstandable and useless
as it is test mailing anyway.
To add unsubscribe links to your mail body, use the footer blocks
which contain this kind of link (note: they are inserted by default
in all mail templates).
When testing a mass mailing before sending the mailing
to the contacts (which well, is always the case),
the local links were not replaced by absolute links,
and the override done on the method `send_get_email_dict`
to convert the link `/unsubscribe_from_list` to the actual
unsubscription link was not working, as it relied
on the absolute link.

1. The merge of the "email_template" module into the "mail" module.
2. The send action of the mass mailing has been moved from the frontend to a cron, because it was too slow to send over 10,000 mails (the user's browser was blocked for 15 - 20 minutes). Mass mailings have now their own process in the kanban view.
3. Mails sent from the mail form are sent immediatly instead of from the mail queue (for instance, when you go to sales > customers > list view > select 2 -3 customers > More > Partner Mass Mailing).
4. Users have now the choice from which mailing list they want to unsubscribe when they click on the unsubscribe link at the bottom of the mail.
5. Mass mailings inherit from their campaign UTMs and mass mailing campaigns are linked to an UTM campaign.
6. Many little improvements
- mail: now trigger postprocess_sent_message in every case, being sent or not, as the state
is propagated in the method; udpated all addons accordingly;
- email_template: fixed URL to edit it in website + form view;
- mass_mailing: barchart now send jsonified value;
- mass_mailing: tweaking the form view with all options
