One limitation is that with the patch lmtp_fallback_relay works
only when the original LMTP destination is an "inet:" destination,
there is no support for fallback after failed unix-domain socket
deliveries. This is an implementation artifact, but fixing it is
substantially more difficult. I don't know how useful fallback
relays are when the primary destination is a local LMTP service.
