Please keep the conversation on the list. I've partially obfuscated the
email addresses in your log extract.

This log entry doesn't prove that. The first line was logged when you
accepted the message. The question is, what was the period from their
making a connection to that point. To get that, you need to make your
logging more verbose. Check the documentation for log_selector (section
49.15 Reducing or increasing what is logged).

You probably want to add some of these: smtp_connection
smtp_incomplete_transaction smtp_no_mail smtp_protocol_error
smtp_syntax_error ident_timeout
