[BUG] mailscanner right conf ?

[darkfritz2]

After install mailscanner there are some issues i've found:

1. in /etc/MailScanner/MailScanner.conf right now is:
   Incoming Queue Dir = /var/spool/postfix/hold
   Outgoing Queue Dir = /var/spool/postfix/incoming

shouldn't it be, like ?:
Incoming Queue Dir = /var/spool/postfix/incoming
Hold Queue Dir = /var/spool/postfix/hold
Outgoing Queue Dir = /var/spool/postfix/deferred

2. i got on mailwatch:
   Please verify read permissions on /var/spool/postfix/hold and /var/spool/postfix/incoming

And the status is red NO for Mailscanner and Postfix

3. i don't understand how spam messages go into quarantine so i can mark them as spam/ham.

Operating system:
Almalinux 8

CyberPanel version:
2.3.9
