--- Comment #3 from Jeremy Harris <jgh146exb@???> ---
The suggested patch has a number of issues, the big one being the affected
period of operation meaning that it hides buggy peer behaviour at other times.

I'm minded instead to limit the scope to after a QUIT has been sent, only in
client mode - but without a controlling option apart from detailed-logging
and debug modes.

Note that we don't know yet if G et. al. even send an SMTP-level ack of the
QUIT, before dumping the TCP connection. Therefore we cannot even tell if
they saw our QUIT (with the current coding).
A debug run of a message send would tell us this.

I'll do some coding based on these thoughts.
Testcase development is also an issue.
