One thing that could be doing this given what you've said is if
Non-digest options -> scrub_nondigest is Yes, the message is HTML only
(not multipart/alternative) and ARCHIVE_HTML_SANITIZER = 0

Another possibility is header_filter_rules with a Discard action.

If the above is not the answer, send me the raw message.
