By default the logs don't distinguish between SMTP serverices
listening on different ports. You need to override "syslog_name"
in master.cf to get service-specific logging.
The commented-out submission entry in recent stock master.cf files
starts with:
#submission inet n - n - - smtpd
# -o syslog_name=postfix/submission
So that log entry might be for the submission port, unless you've
configured it along the lines above.
