The posfix defaults should probably be:

    mynetworks = 127.0.0.1/32

(or for the pkgsrc version, w. ipv6)

    mynetworks = 127.0.0.1/32, [::1/128]

If the users wants to widen the masks or add other interfaces they can
always edit main.cf.  Doing anything else will just leave all the
newbie cable and dsl users open to abuse.
