Ah, but tcpdump taken where? On the server? client? Some middlebox,
which (as Cyborg) pointed out) could be replacing the TLS connection?

And, yes, random drops are an unfortunate feature of today's environment
and do tend to induce log-pollution. Possibly, if this is was which
isn't visible in any way at present, a candidate for log_selector
+protocol_detail ? New since 4.94, that currently logs only
TCP RST received directly after QUIT (a TCP-level protocol violation).

at bugs.exim.org calls them "wishlist".
