[15.0] mail_multicompany default from not being applied

[iTecan]

Module

mail_multicompany

Describe the bug

After installing the module, when we configure 2 smtp servers and send an email, the default mail from parameter is not being applied, being the email from the user the one applied instead

To Reproduce

Affected versions: 15.0

Steps to reproduce the behavior:

1. Config 2 outgoing mail servers that have different domains (@domain1 and @domain2), with from filter being applied
2. In system parameters, config mail.default.from_filter and mail.default.from with one domain (default@domain1)
3. Config a user with an email (user@domain1)
4. Send a mail with a user that is from the company that has the mail.default.from (user from domain1)

Expected behavior
The from in the email header and the resume on top should be the one applied in mail.default.from and mail.default.from_filter (default@domain1) instead of the user's email (user@domain1)

Additional context
We tried using the ir_config_parameter_multi_company (after migration) that is from this repo in branch 14.0 that creates and enviroment for the system parameters per company, but is not being applied either

Hello @iTecan,

Do you have any knowledge if this module is having the same issue in 16.0?

Hello @dg18,
