MX IPs have nothing to do with it. A sender's sending IP often bears

(original sender), no IP or DNS information is appropriate or required.

If my response solves your problem, the best way to thank me is to not
send an "it worked, thanks" follow-up. If you must respond, please put
"It worked, thanks" in the "Subject" so I can delete these quickly.
