Huh?? If gmx.net had an SPF record that stated that only gmx.net and its MXs
were authoritative sources of mail for their domain, and I send something
through hub.org as peter_e@gmx.net, the receiving server, if it checks/honors
SPF, would end up rejecting it as spam ... the only way it wouldn't is if I
could relay *through* gmx.net (I'm assuming that I can't?) so that not only am
I impersonating you, but I'm doing it in such a way that the SPF record
verifies that it is legit ...
