Mailman's "Hold posts" list of patters only operate on message headers.  
Sanitizer adds the headers

X-Sanitizer: This message has been sanitized!
X-Sanitizer-URL: http://mailtools.anomy.net/
X-Sanitizer-Rev: <CVS/RCS ID string>

to each message with no indication of any operations performed, if any.
I'm not sure how hard it would be to modify Sanitizer to add a header
indicating the operations it performed.  It appears to process each
message as a stream, which would make this non-trivial.  You could
probably fix this with procmail, however.  I'll have a look.
