Theres no reason for them to be different between a frontend and a
backend.  (Indeed, it is highly recommended that you compile all servers
in a murder with exactly the same configuration).

A backend may wind up getting TLS connections (via referrals in 2.1, and
from frontends in 2.2).  A frontend also needs an mboxlist.  A frontend
won't use the duplicate db, seen or subs dbs however.
