Me again,

I'm still building my new mail server and I'm struggling getting clamav and 
exim to talk to each other.

I've installed:

clamav-server-0.98.7-1.el7.x86_64
clamav-lib-0.98.7-1.el7.x86_64
clamav-0.98.7-1.el7.x86_64
clamav-milter-0.98.7-1.el7.x86_64
clamav-data-0.98.7-1.el7.noarch
clamav-update-0.98.7-1.el7.x86_64
clamav-milter-systemd-0.98.7-1.el7.noarch
clamav-filesystem-0.98.7-1.el7.noarch
exim-mon-4.84-4.el7.x86_64
exim-4.84-4.el7.x86_64
exim-greylist-4.84-4.el7.x86_64
exim-pgsql-4.84-4.el7.x86_64
spamassassin-3.4.0-1.el7.x86_64

I configured EXIM and Spamassassin. I started the services

exim
spamassassin
clamav-milter

In EXIM I configured 

av_scanner = clamd:/var/run/clamd.exim/clamd.sock
spamd_address = 127.0.0.1 783

However when I tried to send a test email it failed saying

2015-08-24 22:45:13 1ZTzY6-0002f1-OL malware acl condition: clamd: unable to 
connect to UNIX socket (/var/run/clamd.exim/clamd.sock): No such file or 
directory

(gary.ringways.co.uk) [10.1.1.115] F=<gary at ringways.co.uk> temporarily 
rejected after DATA


I've checked and clamd.sock doesn't exist. Nor 
does /etc/clam.conf. /etc/clam.d is empty

Results from Google seem to come up with conflicting solutions, but most seem 
to want to use amavisd which I don't.

Are there anywhere simple instructions on just using clamav and EXIM on Centos 
7?
