[Exim] a newbie needs help...

Well I really screwed up big time. And before I make any further gross errors, I'm seeking the
advice of those much more learned here on this list. I've studied (but obviously not enough) the
various help files and thought I was heading the right direction.... but....

I have a dialup access to my isp (argontech.net). I also have a private network with Exim 3.34
installed on a Linux machine. [See:
http://www.neteffex.com/exim/network.gif
for a network layout of the system.]

Currently, all e-mail for the neteffex.com domain is obtained from the hosting server,
mail.argontech.net. There are no username filters on mail.argontech.net... so if someone
sends an e-mail to "hey-dummy@???" I would receive it.

My desire is to filter out the endless amounts of spam and allow (on the Linux private network)
multiple user names utilizing Exim, and have those user names visible to the outside world
(i.e., bill@???).

Initially, I was going to have all the neteffex.com e-mail deposited in one directory
(/var/spool/bill) on the Linux machine. And then after testing things out, I was going to begin
expanding the Linux local user names.

For the sake of protecting privacy, I was going to send all e-mail to a user "bill".
You can see my Exim runtime file at:
http://www.neteffex.com/exim/exim-configure.txt

I set up a .forward file under /home/bill:
#Exim filter
if $header_to: contains bill then deliver bill endif

The .fetchmailrc file contains:
# .fetchmailrc file for backup.neteffex.home
# set postmaster "admin"
set daemon 240
# Run fetchmail as daemon every 4 minutes
poll mail.argontech.net proto pop3 user "my_user_name" pass "a_big_secret" fetchall

I sent an e-mail out from mail.argontech.net to admin@??? and I picked up the mail
at mail.argontech.net using fetchmail.

I couldn't seem to retrieve the e-mail locally out of the Linux box using qpopper and Kmail (but I
could see the spooled files waiting delivery to a mailbox).... So I tried sending out a few more
test e-mails, (and meanwhile, I was receiving some spam e-mails). After a few days of trying
to send out test e-mails, look what I get from bill@???:

You have spammed over 2,000 emails through my account in the last 3 days.
I have done an IP trace, and turned you over to the authorities.
This is a $2,000 per occurrence fine under Federal Spamming laws,
and up to a year in Federal Prison.

I sent an e-mail to bill@??? apologizing profusely and correcting him (gently) about
his mistaken notion of the existance of spam laws. I assured him that he wouldn't be bothered
any more and that I was attempting to set up mail configuration files and filters.

My Exim activities, however, are stopped until I can work through what happened... and correct
the configuration files. Any and all assistance would be greatly appreciated.
