From what I've seen is that IMAP servers normally take less than 1% CPU load

A host with 256MB of RAM is not going to be doing much heavy lifting
with content inspection.

What about disk? Disk is typically the key subsystem for mail performance.
Fast CPUs don't do much for mail without a fast disk subsystem. At minimum get
hardware mirroring for two disks (RAID 1) and best to make them 1

Hi Everyone,
Thanks for all the comments.
The reason why I said 256MB RAM, is because that is currently what my VM
has...
If I were to take out a dedicated server with:
2.8 Dual Core
2GB RAM

My customer is a business, with 600 staff, however I think they just us

Is more RAM substantially more expensive? 256 MB is rather meek these days.
With physical servers, one typically gets 16G
