You may find it useful to tune your `log_selector` main configuration
setting:
http://www.exim.org/exim-html-current/doc/html/spec_html/ch-log_files.html#SECTlogselector
In particular:
log_selector = +smtp_connection +smtp_incomplete_transaction
The first one will show you connection opens and closes, so that you see
immediately when the connection is closed.
FWIW, I run with:
log_selector = +incoming_interface +pid +incoming_port \
+smtp_connection +smtp_confirmation \
+smtp_protocol_error +smtp_syntax_error \
+smtp_incomplete_transaction +smtp_no_mail \
+tls_cipher +tls_peerdn +tls_certificate_verified +tls_sni \
+queue_time +queue_time_overall +deliver_time \
+received_recipients +sender_on_delivery +return_path_on_delivery \
+all_parents
