Expected Behavior

I would like to include information about the original poster in a DMARC From rewrite situation.

Current Behavior

x-original-from is not included in the blessed set of headers.

Possible Solution

One-line change to _personalize_attrs in Message.pm:
qw/subject x-originating-ip message-id date x-original-to x-original-from from to thread-topic content-type/

Context

Thanks and apologies for the previous bug report not understanding the magic settings to enable templatizing the custom header and footer.
