Look at the full headers of the resulting message and see if it
now has TWO "Subject:" headers.
Exim is more likely to have added a header (permissable) than
modified the original one (frowned upon).
- though you can also re-order and/or remove headers, those are
separate steps.
FWIW, RFC's and smtp protocol aside, deleting or modifying key
headers (Subject:, To:, From:, timestamp, messageID, & routing
information especially) is also prohibited by statute in some
countries.
