IMAP was my particular focus. Both on the server and client side, the
IMAP implementation is not what it could be (e.g. support for namespaces
and shared folders).

LDAP is effectively read-only. It's trivial to search any given LDAP
directory for e-mail addresses: you don't have to understand the
structure of the specific directory because you just do a subtree
search. But there is no standard for updating LDAP directories. So you
can't implement user addresbooks via LDAP (not via the e-mail client,
anyway). An ODBC database connection would be a different matter,
however. I'd be entirely happy if the designer of a GUI e-mail client
dictated the table structure they wanted to use, since I could fake it
with views.

Read-only, see above.
