Bounce-no-mailbox is no longer recommended, as it allows your mail server to be used in Joe-Jobs. It now seems better to delete all mail to invalid addresses rather than spamming the random senders used by spam-bots.
I still recommend bounce-no-mailbox, certainly if you have the qmail- smtpd chkuser patch installed. It's the best way to reject bogus emails at the SMTP level and avoid wasting resources on spam/virus scanning.
With chkuser, is it possible to pull a joe-job? The spammer connects directly to my SMTP server, but I reject it at the SMTP level instead of generating a bounce that I then try to deliver to the actual target (the forged sender of the message).
Please reconsider that recommendation. Perhaps some discussion on the list is in order...
