yes, but it's not a third part :-)

the list manager is appending the footer *after* the multipart's end-boundary. All subparts of a multipart are inside the end-boundary. everything after the end boundary (up to the boundary of any parent multipart) of a multipart is considered to be the multipart's postface. Note that there can also be a preface, which most notably contains something to the effect of "If you are reading this, then it is likely that your mailer does not support MIME..."
