Right, but the docs
(<
http://www.exim.org/exim-html-4.20/doc/html/spec_14.html>) say this can
also be used on routers with more set to false. I added no_more to the
router with no change in the expected error. The default of "Unrouteable
address" isn't even being passed - rather the error is "unknown user"
which I have not defined in my routers. If it were passing the default
error or the error I specified in the last router I could understand and
maybe see where my mistake is.

The ACLs can only apply once to an entire message, right? Thus you can't
have blacklists and whitelists for each individual POP user setup in the
ACLs unless you restrict deliveries to only one address at a time - which
with deferrals you would have some deliveries delayed and with multiple
connections being made using more resources on your server. I learned
this the hard way while trying to implement virus and spam scanning with
options set by users in the ACLs. I was very fortunate to have the kind
souls on this list point me in the right direction. :-)
This has been a big debate with myself regarding whether I should apply
global scanning settings or let my users decide their own settings.
Personally, I would rather set global scanning settings to keep the junk
from entering my mail server but I think letting individual prefs be set
for each POP user is better for business.
While researching all this has helped me understand Exim a lot better
sometimes I feel the water is getting a little bit muddier.
