This is a pre-MIME uuencoded attachment. Mailman does not understand that the uuencoded data is an "attachment". To Mailman, it is just part of the plain text message body. However, I don't understand why adding msg_footer to the body would "break" the mail. Mailman should not be changing anything in the body between the begin and end delimiters so the uuencoded data chould be intact.

No. It is an obsolete method of adding a uuencoded file to an email message and predates MIME. > Is that a correct MIME-set?

Mailman's msg_footer comes after the "end" of the uuencoded data, so what's the problem? > Does anyone have an idea on what to do?

Yes, msg_footer can be empty and Mailman won't add anything. -- Mark Sapiro <[email protected]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
