Ralph,
256M is not a bad start, as long as the System is using less (most of the
time). But I'd look at the size of your users mailboxes (main.mbx, in each
users folder, use Find and look for Main.mbx, then sort by size)). If those
are larger than 1/2 of memory, then disk swapping is going to start getting
out of hand. I'd impose limits on mailbox sizes such that all users are less
than 128M. Maybe even tell those who are larger than 32-64M, to start
downloading or deleting messages. I had a user who had 300M mailbox on a
system with 512M RAM, and there were times that manipulating his mailbox,
slowed the server enough for others (and me) to notice. IMail worked OK, but
there were times that it felt 'sluggish' when checking for new mail. Checked
Task Manager at these times and IMAP4 (that was what he was using in his
client) was 100% CPU for several/many minutes and the disk drive was _real_
busy during that time.
Your new server sounds like it will support at least doubling your
user/domain count, in the future.
