If you are setting the envelope sender as this domain, then get your server added to their SPF record is probably the appropriate thing to do. > At present the message would come directly from sender <at> > theirdomain.com. > > Is there a way within Postfix to have it originate from "distribution > list <at> ourdomain.com on behalf of sender <at> theirdomain.com" or > would I need third party listserv software to do this? You are confusing envelope sender and headers. I think SPF is broken by design, but if you aren't rewriting the email, then yes mailing list software will do that for you. I've tended to regard SPF errors as self inflicted injuries.
