Dear list, We maintain and support an Exchange 2010 server and we recently had an incident that mails originating from our server were not received by the receiving party. Investigating this matter revealed that this was caused by the fact that the receiving party had forwarded his mails to another domain. But since we implement SPF, which states which IP addresses are allowed to send mail with our domain in the From field, and the forwarder does not implement SRS, the destination server saw the mail to be originating from the forwarder and not from us and thus refused accepting it.
We asked the forwarder (a mayor player in the country) to implement SRS in their MTA but they refused, stating that: > We would add SRS support if Postfix started to support SRS officially. > > At the moment there is only unofficial hack available (to old postfix) and > we would not want to use such a solution. Gentlemen, you if anyone can shine some authorative light on this matter: what is the outlook of Postfix getting an official SRS support? Is it completely in vain to hope for it?
