Thanks.
Mailman will add msg_header and msg_footer in one of three ways. 1) If the original message is a single text/plain part, Mailman will attempt to convert the message content and the msg_header and/or msg_footer to unicode, concatenate them and encode the result back into the original message character set resulting in a single text/plain part with the header/footer included. If this fails, go to 3. 2) If the original message is multipart/mixed add the msg_header and/or msg_footer as additional MIME parts at the beginning and/or end of the multipart/mixed message. 3) In all other cases, recast the message as multipart/mixed with msg_header if any as the first part, the entire original message structure as the next part and msg_footer if any as the last part. Note that just sticking the header and footer as additional parts into an original multipart, not_mixed message can't be arbitrarily done. Clearly, if the original is multipart/alternative, this won't work and if it is multipart/signed, it would probably break the signature anyway. In any case, the only multipart structure we know for sure we can safely insert extra parts into is multipart/mixed, so we only do it if the original is multi-part mixed.
