Don't use qmail-inject unless you have to. Use qmail-remote directly.
If qmail-remote reports a transient failure, then inject them into the
queue for later delivery. If qmail-remote reports a permanent failure
then the message cannot be delivered so it can be ignored.
See the qmail-remote man page for driving instructions.
Using qmail-inject will increase your disk I/O and impose qmails
concurrency limits. If you use qmail-remote directly you can bybass
these limits and impose your own :)
