By default Courier only pattern matches against the headers, to get
corrupted messages to match you'd need to search both headers and bodies
by adding the :w line:

if (/^List-Id:.*linux-fbdev-devel.lists.sourceforge.net*/:w)

of course, this is going to dramatically increase the amount of
resources maildrop uses and the amount of time it takes to filter mail.
I'd recommend instead turning off corrupt message reformatting, either
globally (I find it causes my end users more trouble than it saves them,
SA and ClamAV pull out the really dangerous stuff) or for messages
coming from the sf.net mailing list server.
