Re: Does qmail really delay a bounce for this long?

re: qmail not notifying you of temporary failures.  the default time to 
sit in the queue is 1 week.  you can run a script from cron to examine the 
queue at regular intervals and send email to those concerned if email 
hasn't been delivered.

search www.qmail.org for Matt Ranney or Brian Wightman.  Both have written 
perl scripts to do this.  I know of a 3rd script which was posted to this 
mailing list, but i don't see it mentioned on qmail.org.  it was something 
like "qmail-deferred-notifier".
