Every forwarded Email classified as Spam

[haratosan]

Hi there

I use SMF to forward all emails from my second domain to my primary domain (which is hosted by Google)

My Problem now is, that Google classifies EVERY email forwarded by SMF as Spam. SPF & DKIM are set and should be okay.

Is there any solution to this problem? Or have i missed something?

OK, so Google checks the SPF from the origin server. As I can't control this, all mails get classified as spam.

From the RAW-View of the received email:
Received-SPF: fail (google.com: domain of [email protected], does not designate 172.012.123.234 as permitted sender) client-ip=172.012.123.234;

When I send the mails to another email provider it seems to work without problems. It seems like I need to run a full mail server after all.... :-/

I read a little deeper into the topic and saw that you can work around the problem by using SRS (Sender Rewriting Scheme).

PostSRSd is already installed in the container. But it is not enabled by default, is it?

Is there an easy way how I can enable it?
