+The configuration for a @code{mail-aliases-service-type} service is an
+association list denoting how to deliver mail that comes to this
+system. Each entry is of the form @code{(alias addresses ...)}, with
+@code{alias} specifying the local alias and @code{addresses} specifying
+where to deliver this user's mail.
+
+The aliases aren't required to exist as users on the local system. In
+the above example, there doesn't need to be a @code{postmaster} entry in
+the @code{operating-system}'s @code{user-accounts} in order to deliver
+the @code{postmaster} mail to @code{bob} (which subsequently would
+deliver mail to @code{bob@@example.com} and @code{bob@@example2.com}).
