Email Return-Path Setting is not used as Return-Path in Mail Transport #8543
Description
Settings in the adminhtml backend regarding the outgoing mail messages return-path are ignored when Magento initiates the mail transport.
+-------------------------------+---------+----------+------------------+
| Path | Scope | Scope-ID | Value |
+-------------------------------+---------+----------+------------------+
| system/smtp/return_path_email | default | 0 | info@example.com |
| system/smtp/set_return_path | default | 0 | 2 |
+-------------------------------+---------+----------+------------------+
In this case the system/smtp/return_path_email address "info@exa.net" is not used with outgoing transport.
The behavior is reproducible and was reproduced in Magento 2.1.3 and 2.1.4 clean instances.
