Mail stuck in /var/spool/postfix/hold

[Remco Barendse]

2 days ago I had MailScanner working but mail seems to sit in 
/var/spool/postfix/hold until MailScanner tried 6 times and then moves it 
to quarantine.

pyzor was causing a python trace back error but I removed pyzor and that 
solved the error :)  I stopped apparmor just te be sure

There are no errors in any logs, where can I look for clues?

MailScanner --lint :
Your envelope_sender_header in spamassassin.conf is correct.
MailScanner setting GID to  (119)
MailScanner setting UID to  (116)
