Of course, the list is much longer, but original question was about stopping Sobig-F, which sends itself only as a .pif file.
If you want to really filter stuff, look at something like MailScanner (http://www.mailscanner.info) which has file-type/mime-type checking as just the first line of defense. The power and configurability of this system is amazing. It works with postfix and sendmail, and lots of virus scanners - if you choose to integrate one.
For combination with postfix, I'd suggest amavisd-new. It has very good performance, includes spamassassin for spam filtering and works really nice.
