MS keeps sending "Problem Messages" email

[Michal Szymanski]

Hello,

After upgrade of my system, MailScanner started to send, every hour or
two, the following message to local "root":

  Currently being processed:

No trace of files named as above, anywhere in the system (like in
quarantine, queues etc.)

I tried to trace the messages in the maillog and found following
(example for the last message listed above):

Dec  9 18:21:28 sirius postfix/smtpd[1881]: 9985E35238D:

After the message was requeued, the traces of the new ID are as follows:

Dec  9 19:02:03 sirius MailScanner[6927]: Requeue: 9985E35238D.A78A5 to

/usr/bin/procmail)
Dec  9 22:46:53 sirius postfix/qmgr[19287]: 445AD352375: removed


So it seems that it was finally delivered. Why does it appear in these
"Problem messages" emails? How to get rid of them?

regards, Michal.
