-The values contained in these header lines are intended to be used by the
-recipient to detect forgery or tampering in transit, and the modifications
-made by Mailman to the headers and body of the message will cause these keys
-to appear invalid.  Removing them will at least avoid this misleading result,
-and it will also give the MTA the opportunity to regenerate valid keys
-originating at the Mailman server for the outgoing message.
