Thank you Christian. I am running on CentOS 8.2 and the name of the service is "postfix.service". When I enter:
journalctl -u postfix.service --since="2020-07-12 03:06:00" --until="2020-07-12 03:11:00" I see all of the missing data that should be in /var/log/maillog -- almost 50,000 records. You discovered a way to gain access to the missing data! The big question for me continues to be, why did this data not make it to /var/log/maillog?
