How is MailScanner configured. If Postfix is configured to hold incoming
mail, MailScanner must be configured with

MTA = postfix
Incoming Queue Dir = /var/spool/postfix/hold
Outgoing Queue Dir = /var/spool/postfix/incoming

If you want to use the new milter option, you need

Incoming Queue Dir = /var/spool/MailScanner/milterin
Outgoing Queue Dir = /var/spool/MailScanner/milterout
MTA = msmail

and you need to remove the header_checks from

These configuration settings are mutually exclusive.
