[Dclug] Recommendations for Exchange replacement

[Mike Weaver]

FWIW I tried as hard as I could w/ SUSE OpenExchange and finally gave 
up.  I had to replace (for free) two installations I did for clients. It 
does not work as advertised.   I hate to say it but I wound up with 
Exchange, which I hate.  I believe the reason it is so popular is that 
it generates a ton of billing for the techs.

I would like to hear what you put together,

-Mike
