my working Pfix/Mailwatch settings are:

# User to run as (not normally used for sendmail)
# If you want to change the ownership or permissions of the quarantine or
# temporary files created by MailScanner, please see the "Incoming Work"
# settings later in this file.
#Run As User = mail
#Run As User = postfix
Run As User = postfix

# Group to run as (not normally used for sendmail)

Run As Group = postfix

Clamd conf:
Allow supplementary is set to Yes

for Mailwatch/MS:

chown -R postfix:postfix /var/spool/MailScanner/incoming
chown -R postfix:apache /var/spool/MailScanner/quarantine
