[CentOS] Re: 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,

I don't know if you have done it yet, but Fort System's new offering, BarricadeMX, could help you cut spam.

It is closed-source, but FSL gives a lot to open-source communities, especially MailScanner's.
