On my systems (debian) I run mimedefang as user "defang" and
group "defang" while clamd is runing as user "clamav" and
group "clamav". I made the "clamav" user a menber of the
"defang" group so clamd can read the contents of subdirs
below /var/spool/MIMEDefang with group rights.

~# id defang
uid=108(defang) gid=110(defang) groups=110(defang)
~# id clamav
uid=107(clamav) gid=109(clamav) groups=110(defang),109(clamav)
