Hello,
There has been some whispers about considering migrating our mail systems to Exchange Server. I want to try to nip this in the bud.
I would like to ask for some help with providing some kind of comparison of large(r) commercial companies use of email systems... specifically, those using Microsoft Exchange Server, vs those using open source Linux/Unix based systems, including even commercial *nix groupware based systems like Zimbra, as well as plain mail systems like dovecot, or cyrus or courier.
I know that many (if they are smart) Admins that do use Exchange internally will use postfix (or something else linux/unix based) in front of it as their relayhost (for both inbound and outbound), so just counting the number of publicly accessible smtp servers won't be a good gauge.
Does anyone know of any decent non-biased studies that have been done, hopefully relatively recently (last few years) that provide such a comparison?
Thanks,
