email@example.com. This e-mail address may be recognised as a SPAM address by SPAM filters, as it is a very generic email used on all Hypernodes without sane email configuration. Besides that, setting the return-path email designates an email address for all bounced emails. Not changing the default return path (firstname.lastname@example.org) means you will never see your bounced or failed emails and you will never know if there is a problem with getting your email delivered.
Please have a look at this article on how to set a return path in Magento.
Return-path email bug in Magento 2
In a number of cases setting the return-path in some versions of Magento 2 does not work. The setting is ignored and the system’s return path is used anyway. This is a notorious bug in Magento 2 which unfortunately has not been fixed yet although the Magento Community Engineering team is aware of this issue.
Our fix for Hypernode customers
In order to provide a solution for Hypernode customers who experience issues with setting a return-path we have made it possible to override the system return path in a way that it will be kept across migrations between Hypernode plans. The setting is configurable by our customers themselves, so that they can update the default
email@example.com return-path to something else.
You can use the following command on your Hypernode to set the return-path to your own e-mail address via our API.
hypernode-systemctl settings override_sendmail_return_path --value firstname.lastname@example.org
You can verify whether you entered the right return-path with the following command:
php -i | grep sendmail_path
Full details on this workaround can be found at our Hypernode Changelog.
