This happens when the charset or content-type of the footer
is not compatible with the charset or content-type of the
message. In those cases, the footer cannot be appended, so
it's added as an attachment. However, this functionality
has been improved in newer versions of Mailman so you should
upgrade to 2.1.5 and see if the problem still exists.
