I don't know about full Outlook, but Outlook Express cannot. Then again, Netscape doesn't allow a person to use or poll more than one POP3 address without switching identities, and that's a bigger pain for me than limited filtering. For mail where I need more sophisticated filtering, I direct to shell accounts where I can run procmail. I do agree with Charlie Summers about tagging subjects; I belong to some lists that do that, and it's so annoying that I have formail remove the tags. The practice is actually dangerous: if you send a private reply to another member and forget to rewrite the subject without the tag, the other person receives a message with the list's tag in the subject, thinks it's a post (especially if [s]he uses a subject-based filter rule and finds it in the same folder as list posts), and assumes you've said everything in it to the list.
