Handshake is definitely completed: last packet from server is
pure Application Data, and its payload length (170) is very close to
146 bytes of 2-line SMTP banner (it should be slightly greater due to
padding and hmac). So, client drops session just after reception
of this banner. Running Exim with debug should confirm it.

Removal of this 2-line banner seems to be a reasonable next step.
