We're having a bit of a theological debate internally on whether to
implement DMARC on our SRS forwarder domains.
Skip SRS and implement ARC for forwarded e-mails. This should solve
all these problems.
Telling the next hops that they need to parse ARC and trust your system
instead of just checking SPF is a choice that one can make, yes.
Without SRS, SPF will fail on forwarded mail. It is going to be rare for
anyone other than the behemoths to support ARC in any meaningful way for
the near term (0-5 years) and you will always (effectively... ) have
sites rejecting on SPF failures out of misguided "principle."
