3697: Include sensible error messages for LMTP protocol (backport #3696) r=mergify[bot] a=mergify[bot]
Running into the rate limit yields difficult to debug log messages by the smtp container. Specifically the `Temporary user lookup failure` message by the smtp container is misleading.
## Example
Although this is running on Podman, the bugs are in the Python code and almost certainly are not influenced by the host infrastructure. (Leaving aside that I likely have a configuration problem, because the client IP address is not passed along correctly. But the present fix applies nevertheless and is not related to any specific cause of the rate limit triggering.)
