Moving QMAIL to a different Disk?

[Scott Sharkey]

Hello All,

I've got a disk filling up, and I think that qmail is gonna
have to be moved.  Can anyone give suggestions for moving 
the /var/qmail directories without too much disruption? 

I'm assuming that I need to stop incoming mail for a while,
let the queue empty out, and then can move the whole thing
and restart.  Any thing I've missed?
