The patch below may not even compile, but probably works, give it a try.
As you can see, it is mostly a matter of adding a bit of documentation
and disabling conditionals that make existing code apply only to SMTP.

If it works well for you, and Wietse is not opposed to an
"lmtp_fallback_relay" feature, something like this could be part
of Postfix 2.12.

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.

Hi Viktor,

Thanks.  For my specific installations, this isn't a concern as all of
our LMTP deliveries are via inet. ;)

Hi Viktor,

We've been able to start testing this patch. So far, it is working as expected.
