[CentOS] How to size an email server to handle 5 million emails per day
I have no idea as to how to size an email server. I was approached by a customer that wanted a single server with RAID 1 disks to handle about 5 million emails a day. In general terms, what parameters should I take into account to size the hardware specs when the average email is about 10kb, the smalles email is 2kb and the largest email is about 5meg (with attachment) thanks, -- ------------------------------------------------------------ Erick Perez

Would your customer be involved in marketing? I am not sure I want to give advice that will be used to aid a spammer.

I think I would do RAID5 over RAID1 since you'll get more spindles. I'd also consider multiple cores and LOTS of RAM.

On second thought, are mails being delivered locally or are you relaying to Exchange (or similar)?

If you take good measures at MTA level the system backend with SA etc. has only to deal with 1 million, otherwise it has to deal with five times of that. Quite a difference.
