have postfix bounce all but procmail related non-delivery notification

Question

Pardon me for reposting on serverfault; I mistakenly posted it originally on stackoverflow before, and was kindly reminded to post here.....

Problem: I experience every now and then non-delivery messages being sent out when procmail fails. Any non-delivery notification should go out but not those due to procmail errors.

Attempts without the expected

• main.cf: still bounces to external senders

  notify_classes = 2bounce, data, delay, resource, software, bounce
  bounce_notice_recipient = postmaster
  

• master.cf: no bounce messages at all

  bounce     unix  -       -       y       -       0       discard
  

• my procmailrc settings that seem to cause the error (but were working perfectly since the early 2000's until I upgraded to Debian 10 two months ago)

  VERBOSE=ON
  LOGABSTRACT=ALL
  PATH=/bin:/usr/bin:/usr/local/bin
  SERVER=`hostname`
  RECYEAR=`date +%Y`
  RECMONTH=`date +%Y%m`
  MAILDIR=$HOME/mail
  MAILDIRchk="`test -d $MAILDIR || mkdir -p $MAILDIR`"
  BACKUPDIR=$HOME/Backup
  BACKUPDIRchk="`test -d $BACKUPDIR || mkdir -p $BACKUPDIR`"
  BACKYEARDIR=$HOME/Backup/$RECYEAR
  BACKYEARDIRchk="`test -d $BACKYEARDIR || mkdir -p $BACKYEARDIR`"
  BACKUP=$BACKYEARDIR/$RECMONTH.backup
  LOGDIR=$HOME/MailLog/$RECYEAR
  LOGDIRchk="`test -d $LOGDIR || mkdir -p $LOGDIR`"
  LOGFILE=$LOGDIR/$RECMONTH.log.$SERVER
  

• The error message reported back to the sender :(

Question: Is there any configuration setting in postfix such that errors due to procmail failures are not reported -- but still all others are?

It seems that bogofilter suffers from a timeout
