When using LTMP transport for delivery, what happens if LMTP kicks back an error condition to Exim? For instance in the following LTMP conversation:

What exactly happens? Is a SMTP error (4xx or 5xx) generated back to the sending MTA or is it to late by then?
Generally MTAs operate in store-and-forward fashion, so it is too late for this MTA to emit an error on the source SMTP conversation.
If it's too late to return an SMTP error, does Exim handle the 4xx and 5xx at LMTP differently? Meaning a 5xx would generate a bounce and a 4xx would be queued for later delivery attempts?
