Infrastructure for One Million Email Accounts?

Posted by Cliff on from the better-have-good-spam-filters dept.

cfsmp3 asks: "I have been asked to define the infrastructure for the email system for a huge company, which fed up of Exchange, wants to replace their entire system with something non-Microsoft. I have done this before, but not for anything of this scale. Suppose you are given a chance to build from scratch an email system that has to support around one million accounts. Some corporate, some personal, some free. POP, IMAP, webmail, etc are requirements. The system must scale perfectly, 99.9% uptime is expected... where would you start?"

    First posts are overrated. After reading Slashdot daily since 1999, I finally got my first chance at a first post a couple weeks ago, but in the time I needed to post in I didn't have time to read the article and therefore my post was less than insightful. Better to have an insightful post at post 39 than a crappy post at post 1.

    You said,

    "...the email system for a huge company, which fed up of Exchange, wants to replace their entire system..."

    I think perhaps that a parenthetical rephrasing, such as,

    "...a huge company (the subject), which, fed up with (not of) Exchange, wants to replace its (not their, as we want the possessive pronoun to match the subject) entire system..."

    ...might work better. Unfortunately, Mr. Language Pedant has no advice for your email woes. ^_^
