It should be the same on any Unix system. Assume dedicated disks to the
task, one filesystem partitioned on each disk. Simply mount(8) the
disks where you want that space to be used.
I'm not advocating you go crazy and have
/var/spool/postfix/{incoming,active,deferred}/[0-9A-F] as 16 different
disks. I believe this would actually be bad for performance as postfix
moves files between the queues (afaik) so you'll cop a penalty in having
to shift the data around instead of just updating dirents.
Ralf gave a more practical solution - keep the logs, /var/spool/postfix
and the mail delivery spool on different disks.
