Processing email is more CPU and memory and storage driven than seen with databases. Yes, there is a lot of I/O, but that is fairly small footprints (unless you have a lot of IMAP or webmail users with lots of very large mail boxes) which is easily handled by modern hard drive, speed depending upon overall volume.
Memory: Go with 4 GB if you can, not worry so much about the best speed. For example, if 2 GB of the fastest is priced similar to 4 GB of the next speed down, you will get more bang for your buck with the 4 GB. Spool partition: Get the fastest drives you can afford but do not go over board. SCSI 15K drives would be over kill, but SATA II would be great. Either way, try for 10K drives. Hard drives: For an email server like Imail, SATA II drives will do just fine. If your email volume is that great that you need every bit of performance you can get, you are better off splitting the load between servers, such as using gateway servers for primary filtering. Yes, SCSI Ultra 320 15K drives are the best and most solid performers, but you really do not have to have them. Partitions: I would go with 3 sets of mirrored SATA II 10K drives as follows; Mirror1 partition1 system, Mirror1 partition2 pagefile, Mirror2 parition1 spool, Mirror3 single partition mailboxes. On Mirror1 and Mirror2, you will have room for a couple of extra partitions for say logs, administrative and such.
