There is a Ticket about that in redmine. It is basically an issue that Google gives a s*** about a setting that should work around this.

I got a message from a gmail account to my opensuse.org address and tried to send an answer on that message with this opensuse.org address as sender. I configured my email client to send it to my provider, who accepted the message and did send it on to GMail. However GMail refused to accept the message and requires a proper SPL or a proper DKIM signature.

A proper SPL would mean that I should not send the message via my provider but via a system that is authorized by SPL to send message with an opensuse.org address as the sender. Most likely a server owned by (open)SUSE.

I am working to enable singing certain messages with my own DKIM signature, but I don't know if GMail will accept such a message, because there is no relation between the DKIM signature and my opensuse.org address.

Signing the message with a DKIM signature of opensuse.org would mean that I should have the secret key of that signing certificate.

Any thoughts about other solutions?

The only proper solution is to create at least a proper SMTP server at opensuse.org to send those emails.

The idea floats now and then but gets not enough traction.
