well i've only got about 25k accounts (but considering it was only ~14k
last year i'm trying to plan for the best), but right now i serve all
mailboxes and personal webspace via NFS from an ext3 partition on a
fibre channel SAN. I've had no issues as of yet (and a few of the
mailboxes, like mine push a gig), although courier seems to choke on my
mailbox on occasion, but i'm also on an older version.

and if anyone is interested ... i'm getting ready to try a basic LVS
cluster (redhat's cluster with 2 load balancers on top of 4 mail servers
that all directly access a san via fibre channel) with gfs as the file
system. ohh and i do realize its probably a bit over kill, but i'm
trying to plan for high availability.

*crosses fingers* i'll try to remember to tell how it fares, if anyone
is curious and i havent said anything feel free to yell at me, project
should be done over the next month or so.
