It is not a misconfiguration on the recipient side. The final recipient does exactly what it needs to do, based on your SPF record. If there is any kind of misconfiguration, it is in your perception of how SPF works. SPF breaks forwarding, unless SRS is used by the forwarding MTA. It really is that simple. It is not the job of the MTA to encapsulate messages before forwarding them, as Sebiastian suggests, and mail servers that forward the message as is are not 'lazy', but working as intended. As for errors in your Postfix configuration, you posted a SPF question, with no Postfix component whatsoever. No configuration details, nothing. It is impossible to judge whether there are any errors in it. Mvg, Joni
