ClamAV .85 & Exim 4.50 - With or without Mime checking?

I'm using Exim 4.50 and installed ClamAV .85. Virus detection seems to be working fine with minimal effect on performance on a VPS. However, Exim will not restart unless I omit mime checking from the Data ACL section of exim.conf. By omitting the following

demime = *

Exim starts. If I leave this line Exim stops and won't restart. Attempts to restart put out this error:

Starting exim: 2005-05-16 22:19:06 Exim configuration error in line 558 of /etc/exim.conf:
error in ACL: unknown ACL condition/modifier in "demime = *"

Comment out the line and Exim starts right up. According to instructions, the complete Data ACL section should like this:

deny message = This message contains a virus or other harmful content ($malware_name)
demime = *
malware = *
accept

ClamAV seems to be doing fine based on virus test messages not delivering and rejection details in the logs. So what am I missing out on by leaving out mime checking with Exiscan and ClamAV? Or is this by design with Exiscan and DA? Should I just leave well enough alone?

Suggestions appreciated.

According to what instructions, found where?

The error indicates that the command isn't recognized by your version of Exim.

I used these steps except that I skipped the crontab for freshclam (and a manual install of Exiscan since it's now integrated). I realize this info is a bit dated but it closely matches what I read elsewhere for Exim and ClamAV in environments other than DA, so I figured it would be close enough.

Other info that I gathered includes

edit: "demime = *" is depricated, at least with Exim 4.51.
