Here's the problem, taken from your trace. This is in a block of data
you are sending to Exim:

                         206e 6f63 6820 6569 6e20 6765 6e61 7565
                         7320 4578 7472 616b 7469 6f6e 732d 2075
                         6e64 2050 4352 2d50 726f 746f 6b6f 6c6c
                         2061 7566 7461 7563 6865 6e3d 0d0a 2e2e
                         0d0a 2e0d 0a4c 6965 6265 2047 723d 4643
                         ^^^^^^^^^^^^

>>>This sequence is>>> CRLF . CR LF


                         3d44 4665 0d0a 0d0a 5374 6566 616e 0d0a
                         2020 2d2d 2d2d 2d55 7273 7072 3d46 436e
                         676c 6963 6865 204e 6163 6872 6963 6874


Well, CR LF . CR LF marks the end of the data phase. So Exim was right
to conclude that the message was finished.

Note that just before this, there is the sequence CR LF . . CR LF
which is the correct way to send a line that consists of just one .
character. Looks like the sender inserted the escaped sequence, but
forgot to remove the original text. Or something....

Exim has reponded OK to the end of the message, and then complained
about what follows. Here it is:

                        ..^X ..^@ .... ^@^@ ^A^A ^H^J ^K..  z^?
                         ^G.. ....  2 5  0    O K    i  d =  1 7
                          a X  P n  - 0  0 0  5 T  k -  0 0 ^M^J
                          5 0  0    U n  r e  c o  g n  i z  e d
                            c  o m  m a  n d ^M^J
