I'm willing to give it a try (in a limited fashion) at the moment,
given the amount of direct spam from (uunet et al) dialups.

This is a simple matter of decent configuration on the MTA

ie for Exim
--[ exim.conf ]--
# We'll just log for this one
rbl_domains = "rbl.maps.vix.com:dul.maps.vix.com"
rbl_except_nets = "x.x.x.x/y:e.e.e.e/t"
rbl_warn_header = true
rbl_reject_recipients = true
#rbl_log_headers = true
#rbl_log_rcpt_count = true
--[ exim.conf ]--

This config would reject on the basis on the RBL and DUL but allow two
ranges through regardless.

The question here is are we required to accept email from any source
on the net?

My personal view is no, I'm quite happy to allow dialups to attempt
SMTP transactions direct.  I'm not of the view that we should block
port 25 outbound at the router, however I do firmly believe that I
have the right not to accept connections from dialup ranges.

If someone is attempting to make direct connections then they should
be clued enough to configure a fallback through their local SMTP
relay.  If they aren't then they shouldn't be attempting direct mail.
