Re: How do I use anti-spam features of Exim?
Somewhat oblique response. I have a similar configuration -- dialup,
dynamic ISP, fetchmail & exim deliver. I'm given to understand that
many MTA-based spam traps work better if you're not ferrying mail from
another caching point, such as a POP3 server. In my case, my ISP
(Mindscape) runs a service called spaminator. I've taken to bouncing
spam to an address configured for this purpose, though I'll admit it's a
bit of a black box WRT what it actually does with this information. It
appears to use a source address and (spam) program signature heuristic:

I've toyed with a number of other alternatives, including setting up a
local "white/black/grey" list type filter. Haven't yet. This also
addresses only the reading issue -- all content is actually delivered to
me. WBG filter involves lists of known good and bad addresses (white
and black, respectively), and all others, classed as "grey". The trick
is list maintenance. There are a number of systems set up to handle
this. It's probably a resonably decent approach.
Procmail recipies are another option (and often are part of a spam
solution), though I find them a bit hard to maintain, and long.
