Hi Tom, > So please excuse my ignorance, but what is "SRS?"
What you are doing constitutes as forwarding, and that means that SPF validation results are invalidated. To your rescue, you won't be changing any of the headers customarily signed with DKIM, so you'll probably get through DMARC validators. SRS is a technique to "fix" SPF failures due to forwarding, by replacing the envelope sender with one on your own mail server. It will however not be taken into account during DMARC validation, which not only wants SPF to pass, but also have a match between envelope and header from addresses. https://www.libsrs2.org -Rick
