Say you are responsible for setting up an email solution at a company. Which would be your choice? I know of the following options, but many of them not well:
- Gordano Mail System
For having used it a little over two years, I really, really like Gordano Mail System. A fair bit more than Exchange, I must admit, but I'm biased against Microsoft, so I am not a fair judge. GMS lets you modulate what you need: it comes with email/aliases/calendaring (and good logging), and you can pay for support/upgrades, anti-spam, anti-virus. Their support is top-notch, their KB comprehensive (and, I will admit with a touch of pride, I have contributed, with my questions, to the addition of a few articles in there). Although, if you need a Blackberry Exchange Server, or something similar, I'm not sure what you should go for.
I've never gotten to play with the Google Apps but I've heard a lot of good from that, too (despite my personal belief that Google is Big Brother :) ).
So.. What would your choice be? Why? I've never played with a more DIY email solution, but I'm sure many people here have and wouldn't trade their setup for the world :)
