You hint at the failure mode that you're trying to protect against, but
it would be more helpful if you stated it explicitly: What is it that
you want to protect against failing?
Direct answer:
Can't be done with stock qmail. I know of no attempts to patch qmail to
do this.
Alternate solution:
Put the queue on an external RAID. Still need to connect to it by SCSI,
but failure of the server hardware won't result in loss of the queue.
Just hook up the backup server to the RAID, reboot, and fix the queue.
Again, what it is that you're trying to protect against?
Moving the queue to NAS implies that you want to continue operations
independant of server hardware. Is that correct? Or is there some
other failure mode that you're trying to protect against?
