[From qmail man pages]
doublebounceto
User to receive double-bounces. Default: postmaster.
If a single-bounce notice is permanently undeliver-
able, qmail-send sends a double-bounce notice to dou-
blebounceto@doublebouncehost. (If that bounces,
qmail-send gives up.)
In the file /var/qmail/control/doublebounceto you may have doublebounceto defined as "postmaster". You may wish to change this to a null account, or create another account to receive double bounces, then create a cron job to:
#!/bin/bash
/bin/rm -rf /home/e-smith/files/users/%username%/Maildir/new/*
You may have to modify the template directly:
pico -w /etc/e-smith/templates/var/qmail/control/doublebounceto
[Change and Save]
Then expand it:
/sbin/e-smith/expand-template /var/qmail/control/doublebounceto
Hope this helped,
