There are two issues here. Both Scrubber (replacement of attachments
with hyperlinks) and Decorate (addition of msg_header and/or
msg_footer) manipulate the message content and create new
Content-Type: headers in the process. Content Filtering may do this in
some cases too.

Then, I think the underlying Python email library doesn't support the
'format' and 'delsp' parameters when getting a decoded message part
body from a message.

You might be able to avoid the problem if you set scrub_nondigest to No
and make sure both msg_header and msg_footer are empty, but this may
not be satisfactory for other reasons.
