Why are my email headers getting me spam boxed?

Question

Can you please advise me on what is wrong with my headers that is getting them spamboxed by gmail and almost all mail providers?

Please note I changed the domain in the header for security purpose the real domain is: bounce@LDSDevotionalLetter.com

David,

I've been hoping to get together with you since we met up a few months ago.
I'd like to take you out to lunch! there is a great fish taco place on
santa monica boulevard. Give me a hollar!

Thanks,
Jason

SpamAssassin objects to the header "X-Mailer-RecptId" - it literally penalises people for this, though Interspire uses it for bounce processing and other things.

However, X-Mailer-RecptId is used only by Interspire so it's a bit unjust that SpamAssassin is penalising Interspire users for the sins of others.
