I won't make your decision for you, but can give you a few more things to think about. "Mail server for 4000 accounts": this could mean a lot of different things: it could just be forwarding mail elsewhere, it could be handling POP3 users downloading mail, it could be handling POP3/IMAP users leaving mail on the server (or a mixture of all of these). This makes a big difference. Webmail interfaces can also put a big load on the box. The total number of users is mostly important to planning storage capacity. It's more useful to know the total number of concurrent users: if 90% of the userbase checks their mail at 9AM, that is what you must plan for. A couple of pointers though: If you don't want to take the box down to replace a failed hard drive, the DL385 is a much better option. If the box is just forwarding and isn't storing user data, maybe it's better to have a couple of the smaller boxes and CARP them. Hope this helps.
