That won't work here. Marc's customers are the mail recipients. They can't get
all Marc's servers added to all SPF records in the whole world. There are two
possible solutions: envelope sender rewriting or adjusting the SPF policy on
the destination (meaning: adding Marc's servers as permitted senders for all
domains (perhaps that was what you meant) or applying the SPF check to the
server that delivered to Marc's servers, e.g. by adding Marc's server to
internal_networks). Stubbornly demanding that the envelope sender address be
unmodified without adjusting the local policy is not going to work. It's the
same thing as demanding that the envelope sender always be trusted by
everybody, but we know that it can't be.
