Don't worry about inodes, just don't use the defaults to newfs when building the filesystem. I didn't intend to go quite so high, but I ended up with over 90 million inodes on a 91GB filesystem. Currently, with ~4600 accounts: Filesystem Size Used Avail Capacity iused ifree %iused Mounted on /dev/da1s1e 91G 5.7G 78G 7% 337904 95163918 0% /var2 I know that some believe that replicating/backing up a mailstore is good practice, but having suffered a lost system once, I found that it's not worth the hassle, as the mail lost wasn't backed up since the early morning hours, and the mail that was restored was already received by the users. Learning from this, I now use RAID5 (a simple mirror would work as well) to keep my mail, backing up configuration and passwd files only.
