Trying to figure out Proxying with LMTP to a few back end storage servers for quota checking before accepting email delivery on the front end nodes.
If I connect to the back end server directly via telnet, everything works great.
If I use a front-end server to proxy to the back end server, I don't get the same result.
Running 2.2.4 on both front and back end servers.
Any help would be appreciated.
