[AccessD] OT: Messaging Servers

Can anyone recommend a low cost (free) Messaging server, ala 
Exchange Server?

I have be asked if I know of any, but I don't. I hope someone out 
there will know.

What they are specifically looking for is something that can handle 
e-mail and calendering functions. If it was just e-mail I'd 
recommend Mercury, but with the calendering thrown in there, I 
have no ideas.

Any takers? Any ideas?
