The milter has to pass the "-c username" option to spamc. I'm not sure
if SpamAssassin would be able to read per-user configs unless the
milter user had permission to launch spamc in setuid mode.
Also, if you use the "-x" option to expand aliases, the milter has to
call "sendmail -bv" -- an operation the requires root or TrustedUser
The ClamAV milter runs as user "clamav," but it doesn't have any
setuid code because there are no per-user settings.
