[Mailman-Users] Footer shows up as attachment

[Schwartz, Robert - IS]

I'm adding a footer to every email to allow user to unsubscribe.  It is showing up as an attachment.  I've set Should Mailman convert text/html parts to plain text? This conversion happens after MIME attachments have been stripped. To yes.  But this is not working.  When I post to this website my message is sent back with a footer to unsubscribe which is exactly what I want.
