Attachment is a very vague word in this context. What happens to list
headers and footers depends on the MIME structure of the message. Most
messages that have what are normally called 'attachments' have a main
MIME type of multipart/mixed. For this type of message, Mailman will
add the header by inserting it in a text/plain sub-part as the first
sub-part of the multipart/mixed message and will add the footer by
inserting it in a text/plain sub-part as the last sub-part of the
It will not add the header and footer to the 'attachment'. Whether the
header and footer appear as inline text along with the 'message body'
or as separate attachments is entirely a function of the MUA used to
view the message.
