the HP DL180G6 is a nice box for those requirements. 2U server that can be configured with up to 2x6 core Xeon 5600 series processors, and up to 96GB ram without using really expensive memory (has 12 memory slots, 6 per CPU socket, so 6x8gb gets you 48GB, 12x8gb gets you 96gb), and has either 12 x 3.5" SAS/SATA or 25 x 2.5" SAS/SATA hotswap drives.
a million emails/day is an average of 12/second every single second of the day. I'd wager your file system had better be able to handle 3-4 times that so that bursts are handled gracefully. I'd definately recommend using raid10 with a fair number of disks for this as that's lots of small file creates.
Your other problem will be dealing with all the spam you'll get if the email addresses are visible anywhere (and maybe even if they aren't).
