Hello!
 
I have the same Problem on my Server. If I restart Mailscanner, the Mails
are scanned and deliverd.

Subject: MailScanner stops delivering e-mail to Postfix

      After upgrading MailScanner to version 4.45.4-1 (Mandrake
      2005) I have noticed that my mail gateways seem to be
      stopping delivery at random times.  After a lot of time
      searching for a postfix error I am starting to think that
      something may be wrong with MailScanner. 
 
Symptoms:
1) Postfix accepts the message and places it in the hold queue. 
MailScanner scans the message but never gives it back to postfix.
It remains in the hold queue forever.
2) I see e-mail in the queue that is several days old.  MailScanner
moved all of the e-mail from that day except for a handful of
messages.
3) There are times when postfix will run with a certain number of
messages in the queue.  I'll check it in the morning and see 59
messages (for example).  E-mail will deliver all day and that
evening the same 59 messages are still in the queue.  I can usually
identify the problematic messages after a few days because they are
much older than current e-mail.
 
If I manually move the messages from /var/spool/postfix/hold to
/var/spool/postfix/incoming they are immediately delivered.  Last
night around midnight I dumped 3,000 messages from Friday and
Saturday just so they could be delivered.  I saw a similar thread
in the archives and checked to make sure our DNS lookups are
working properly.  Has anyone seen this before in this new
version?  The previous version was rock solid with no delivery
problems to speak of.  If I can't find an answer soon I will have
to revert to the previous version.  I appreciate your help!
