I tried putting a spool folder on a second drive/controller and it never
really worked. I was still getting files and logs writing to the old
spool folder. It never seemed to completely move over to the second
drive and constantly had problems. I ended up just switching it back to
the default.

Is there more to it than simply changing the location of the spool
folder in Imail Admin?

good,  but note before and after swappping params.

but what service in Imail swappable? none I reckon.  they must all be 
locked into RAM and never swapped.

yep, imagine iwebmsg (or imap) process needing to repeatedly scan the
mbx 
file to pick up all the headers and chop them into 25 or 50 per html
page, 
then the user deletes some msgs, and the whole re-read of the 100 mb
file 
starts over again.  For just one iwebmsg user with a 100 mb file, he can

pretty much put the disk drive on its knees.  I don't know how iwebmsg 
handles in memory the msg headers of a 00 mb .mbx, but I'm bet they
aren't 
kept memory, so the disk , for just one user, will be extremely busy.

This is a situation where 160 mbyte/sec SCSI disks with 128 megs of 
on-board controller cache really helps.

And having the imail spool directory on a separate controller+drive from

the mailbox controllers+drives.  and if you have to swap (argh!!), have
the 
swap on a separate controller+drive, or at least in it own dedicated 
partition.  Nothing worse than a fragmented swap space.

and of course you don't want ANY swapping going on in a dedicated
mailbox 
server.

wouldn�t that be nice.   Let us know.
