Hello,

I use Odoo V15 and odoo studio.

Here's my problem: when you send an email to several recipients using Odoo templates, the email is sent via the "catchall" in the name of the user who initiated the action in Odoo. The various recipients and the people copied do not appear when the email is sent. So the recipient doesn't know who else he's talking to. 

For example: an internal user (user 1) sends an email containing a price request to contacts A and B of supplier 1 with another internal user (user 2) as a copy.

Contact A (from outside Odoo) will receive an email from Catchall in his inbox as "user 1" but the other recipients of the email (contact B and user 2) will not appear. Contact A is therefore not informed of the other recipients of the email and does not know to which contacts he will reply.

How can we ensure that all the people in the email chain are informed of the different people in the email exchange (including external people)?
