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?"

    LOL. Actually, it's my job :)

    I designed a system, based on FOSS, that could handle this kind of load, scales nicely, is standard and buzzword compliant, elegant, flexible, and is tested (although not on this scale).

    Guess what - I'm not posting the howto here :)

    As someone working for said company:

    Please, please, please! What ever you do, do NOT use Notes. Any value gained by not having as many viruses is very quickly lost by all of notes quirks:

    • Lost mail. I get severe disconnects between my local and server replicas. Server has stuff I don't and vice-versa.
    • Calendar very frequently forgets things, gets out of sync (it will say a meeting is at 10:00 when it is at 8:00).
    • Crashes several times per month.
    • Will NOT alert you of upcoming meetings when it is locked. My company requires a timeout and then it locks the screen.
    • Archiving and backup sucks. Be prepared to copy lots of .nsf files that you might not even be able to open any more or otherwise Notes will complain.


    Please, I beg you, DO NOT use Notes!
