That might help. I put the option in for exactly this type of reason.
Instead of calling fsync after the delivery it lets the OS manage
the disk buffering. You might also want to comment out the fsync's
in the qmail source code. These two changes will let the OS manage
the disk buffers instead of flushing them all the time. You'll get
much better disk performance.
