[Mimedefang] Using ClamAV with default run-as-user settings

[Kenneth Porter]

The ClamAV RPM installs with the assumption that the services will run as 
user "clamav". MD's RPM assumes that it will run as user "defang". Changing 
ClamAV to comply requires changing ownership of a couple of directories and 
editing the /etc/clamav.conf file.

It seems to me that it would be simpler if MD made its directories and 
files group-readable (using group "defang"); one could then add clamav to 
the defang group. The MD RPM could check for the existence of the clamav 
user and add it to the defang group.

Is there a problem with setting things up that way that I'm not seeing? Any 
pointers on where to tweak MD to test it?
