Unfortunately I was unable to reproduce a working environment.  It's
still on my to do list but I've been over tasked over the last couple
weeks and this was a lower priority.  We will be setting up a new
environment in the next 30 days and are hoping to tackle our problem
then.  We are getting new hardware which will free up more hardware as a
test environment.

I've got a similar problem. Can I clarify what this solution means,

It looks like we need lmtp listening on a TCP/IP socket at the back end,
course. I've got that.

At the front end I'm delivering into a unix socket, so I have that set

But does the solution below suggest that I also need to set up a tcp 
listener on the front end? Perhaps that's the process that's doing the 
final delivery?

Or is the solution below one line for the front end and one for the back
