Check your header_checks file for IGNORE rules.
Ah, thanks very much. I should have known to check for something like that.
Why would someone add something like this?
/^(R|r)eceived:.*in.*$/ IGNORE
/^(M|m)essage-(I|i)d:.*in.*$/ IGNORE
Outside of the obvious reason to purposely prevent them from being
written to the message, what use does this have? Strip any
non-internal headers for privacy, perhaps?
Thanks,

External headers should never be removed. The lines are
probably someone trying to remove internal headers -- a
questionable practice in itself. But they botched the job.
I would strongly suggest removing both rules.
