FWIW: sendmail had the inverse problem and it was resolved by marking
an "interface" as optional:
DaemonPortOptions: Modifier  Options (flags) for the daemon
   O         optional; if opening the socket fails ignore it
This was done so a (generic) cf file could have both IPv4 and IPv6
DaemonPortOptions (sockets) without failing to start when IPv6 isn't
available.
