what i've seen.. Re: [olug] MS Exchange alternatives

[Brian Wiese]

Eric,

I've never seen anything free (as in free beer) to wipe out exchange on 
M$ with a gnu/linux solution... and if that ever happened, I'm sure we'd 
all hear about it. =)

http://www.bynari.net/ - InsightServer

else best bet is to look for an alternative groupware solution (likely 
web-based), so that they can migrate off of the M$ Outlook platform for 
everything.  Email would likely go to an LDAP and any client 
(Thunderbird?).  Collaboration, room reservation, etc.. is likely 
web-based and may be a little slower in reaction speed, but (if a 
concern) then you can access anywhere, any platform, etc.  Find out what 
specific Exchange functionalities you need (calendar, tasks, messaging, 
project mgmt..) and I could prob dig something up.  I've been casually 
looking at this for some time, here's what I've found...

note: single sign-on may be a problem =(
note: I've found a few good single-purpose apps (calendars w/vcal, etc) 
but no 'exchange replacement'... this is apparently the "Holy Grail" in 
GNU/Linux migration to the office space
