Given they way I access my email can I uninstall things like procmail, sendmail, and various MTAs? or is this likely to break something else?
Probably. If you remove sendmail, you may find that some local processes are broken until you install another MTA. nullmailer and ssmtp are both small ones that just forward to a remote host.
I'm thinking of using 'mailfilter' (mainly because it can act as a POP3 client) to scan the mail headers on the ISP server and delete any spam before I download it.
Yes, I've used that in the past. I think it can use the DNS blacklists to delete spam. Remember, there is a relatively high chance of rejecting non-spam without ever knowing if you use DNS blacklisting. Also, you should whitelist mailing lists, as you will probably be removed if you send a "Hi! I just rejected your email!" message to a listserver.
