AMD XP1700. 1.4 GHz. The disk is a Seagate Barracuda (ST3802110A). Nothing special, this isn't a huge corporate server, just my own hobby. > Is there no ability to select a range in the IMAP commands, seems > strangely inefficient to select the entire box, or is this just a > limitation of IMAP in genera? The SELECT command is used to select which mailbox is active. When issuing the SELECT command you're not at the point of selecting which messages yet; that would be FETCH. >> Server-side sort is a huge win for webmail.

It's been a long time since I've delved into it, my Real Life has really slammed my development time. > Can you explain, technically, why sort is more or less a requirement?

I could, if I had any folders that big, but I don't keep that much stuff around. I'm sure there's plenty of Cyrus and Courier benchmarks out there though, and plenty of "mbox vs. maildir" comparisons. Gonna have to do a little Googling on this one, methinks.
