Yes, there was!
This is a Sendmail setup that I converted into an Exim setup, so a few
unclear areas still existed due to my lack of any knowledge on Sendmail.
Anand Buddhdev is to blame... he did not allow me even one day to learn
anything on Sendmail before he converted the setup to Exim (it was 1.0.x
those days) ;)
So the rule that was giving me all the spam turned out to be the one
below, and the inverted rule below it seem to have fixed my problems
with spammers..
#accept domains = +local_domains : +relay_to_domains
# local_parts = postmaster : abuse : hostmaster
deny domains = !pri.host.name : !default_qualify.dom.ain
local_parts = postmaster : abuse : hostmaster : uucp : root
It turned out that those local_parts on the virtual domains were being
mapped to pri.host.name and default_qualify.dom.ain. Denying those
local_parts for all virt.ual.domains seems to be a cure as I look deeper
into the path I took migrating them from Sendmail...
As they always say, "with Exim" everything is possible!
cheers
