I am not a zimbra employee, just somebody who is very happy about my recent Zimbra rollout... I run Zimbra against an external LDAP directory, which also serves as the AUTH server for my Samba PDC.
Don't speak on things you don't know...
Yes, they both do email...
They also both do:
Calendaring (shared, free-busy)
Address book (Shared if you like)
Resource bookings
Mobile Sync to phones (no blackberry, just like Exchange, you gotsta pay da man for that)
Web interface
Global Address List
Zimbra does, that Exchange doesn't...
Automatic brick level backups (even if it is only to it's own drives by default)
Free integrated Anti-spam (not sure if Excahnge has this yet)
Free integrated Anti-virus
iSync connector for iCal and Apple address book
Lots of cool Zimlets (google maps that recognize an address in an email and will map it for you, Skype plugin, asterisk plugin in the works I believe)
