There are a couple of programs that are designed more or less specifically for use with uupc, given its dominance in the free UUCP field. Of these, UUPC Setup attempts to simplify the otherwise irritating ResEdit-based setup in uupc, Mail Call notifies you of new mail, UUCPShare and UUCP Monitor merge the old and the new by linking UUCP and MailShare (an SMTP server for the Mac), Dave Platt's Fernmail checks in as a competent mail program, TheNews works as a decent UUCP newsreader, and finally Robert's File Transfer copies files via the UUCP protocol.
