I really believe selinux not an issue in this case.

/etc/MailScanner/MailScanner.conf: Run As User =
/etc/MailScanner/MailScanner.conf:Run As Group =
/etc/MailScanner/conf.d/CNM-MailScanner.conf:Run As User = postfix
/etc/MailScanner/conf.d/CNM-MailScanner.conf:Run As Group = postfix

I have seen you advise the -U many times in this discussion group.
I have always been hesitant to allow unsafe operations, favouring
fixing them if possible.

I do see something is changing group of /var/spool/MailScanner/incoming to:
 drwxrwxr-x 9 postfix clamav 4096 May 17 12:50 /var/spool/MailScanner/incoming/

I have tried to change it to postfix postfix but it changes back to as above.
(To change I stop postfix, MailScanner, and clamd; make changes; start all)

Worse, I think, is I see this:
drwxr-x--- 2 postfix clamav    4096 May 17 12:45
drwxr-x--- 2 postfix clamav    4096 May 17 12:47
drwxr-x--- 2 postfix clamav    4096 May 17 12:50

Are you aware of any unsafe perl code that is involved in this
situation that if allowed to run would fix this problem?

Kind Regards
