I would use an SQL backend, mysql, oracle, postgresql.
SQL engines are much better at transactions than ldap servers,
unless ldap is a frontend to a SQL engine.
For the price, you can't beat a master mysql server replicating
to "read-only" copies on a set of frontend email machines talking
to a backend data store ( NFS or SAN ).
