It's with v2.0.14 on both director and backend lmtp servers.

I now tested with:

	process_limit=10
	client_limit=1

on both directors and backend lmtp servers, but I'm still getting
these same failures. Since you're hinting about "lmtp proxy bugs",
I think I'll try if it works better to skip the director/proxy and
just have postfix deliver directly to backend lmtp-servers directly.
