Agree strongly with PostFix+Cyrus. It is a very solid e-mail platform
and it provides delayed expunge and unexpunge (data retention), shared
folders included shared seen state, full-text indexing, and quotas.

I'd discourage this. LDAP is great, and OpenLDAP is a solid DSA, but
LDAP makes a miserable "groupware" platform. No client other than
Evolution supports updating LDAP, every other client is read-only. And
no clients agree on schema. It's pretty awful for usability.

One needs to carefully define what you need and what features you want.
"Calendaring" is very vague. Do you need resource reservation, conflict
detection, participant roles, etc... For addressbooks GroupDAV is
reasonably supported by most clients at this point (including
Thunderbird). Calendering is more complicated. Most importantly, you
*MUST* have GroupDAV or CalDAV for group calendering/collaboration -
iCalendar is *not* a groupware solution, it just doesn't work for
