spamd_address = 127.0.0.1 783

Then you just add the spam rules on the mime ACL.

The main point is that Exim ACLs really rock. You can do everything there,
ranging from SPF, Greylisting, spamassassin and av, mixing them to your
delight. I can easily say that I don't want to check for spam or greylist
authenticated users, unless they come from a give network and are
sending e-mail to domain X. You can use some very interesting variables
on the acls for control, something like:

  warn    set acl_m2 = ${lookup mysql{GREYLIST_TEST}{$value}{0}}

and then I can test for it:

          condition = ${if eq{$acl_m2}{0}{1}}

I actually build my own (rpm), since centos stock one isn't compiled
for mysql nor spf.

If you want to take a look at my rpm, contact me off-list and I'll
give you the url for download.
