The remote server is for some reason being tardy in sending back the
"I've got it" response.

But it seems to be Exim, and Exim sends the response immediately after
writing that log line. So, what could be wrong?
(1) The response is getting lost. Not too likely repeatedly.
(2) The receiving Exim is doing a lot of processing between receiving
the "." line and finally accepting the message. It could be running a
DATA ACL or a local_scan() function. Is this the case? The message is 6M
long, so if some kind of scanning is going on, that could be the cause.
My money is on (2). You could try increasing the timeouts on the sending
host.
