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 10K or 15K rpm models. 7.2K rpm disks might not cut it for 600 users unless you go hardware RAID 10 with 4 disks. > how much would that handle? With the right disk subsystem, those specs above with Postfix + Dovecot IMAP + antispam stuff + etc should be plenty. > My customer is a business, with 600 staff, however I think they just use > a single broadband connection so that will be the limiting factor, as > this dedicated server has a 100Mbps link to the net.. What is the up/down link speed of the broadband connection? If's it's something like the low ball minimum 1.5M/512K the speed of the server won't mean much, just as you surmise. And if that is the case, this smtp/imap server should be placed on site at the business location, not in a colo. Where is their current mail server located? Also, you need to get some usage data from their current server to find out exactly what their flow volume is. -- Stan
