On the mailing list this is done by the mailing list system, mailman,  
which is in ports/mail/mailman.

But the cleaning stuff is just part of a much larger system (mailing  
list management), so I don't think you can get it to do what you want.

There is a milter,

  ports/mail/mime-defang

which, while it can do many other things (that you don't need to  
enable, also does this.  I haven't used it in more than 5 years, so I  
can't speak for how well it works.  But I did set it up for an  
organization that had lots of Outhouse users on desktops that were  
vulnerable to malicious HTML.

mimedefang is also useful for blocking certain types of attachments as  
well.

There may be better, special purpose tools that do what you want.  You  
could also look at the mailman source (python) to see how it does its  
cleaning.
