Redmine

Hello All!

Before, we used Redmine 3.4 and we could send emails with subaddress in BCC to open a new issue in the desired Project.
But after upgrading to version 4.1.1 this does not work anymore.
For example, before we could send an email with BCC:redmine+kitchen@email.com and the email would land on the Kitchen project.
But after upgrading to version 4.1.1, the BCC:redmine+kitchen@email.com will arrive at the default project "House".
If we send as To: or CC:, no problem.

Could you please help me?
