Postfix error loop every two minutes

Hi, I’ve been configuring postfix and have done some successful testing, but messed up somehow with a test email. Below are five lines from a looping entry in /var/log/mail.log that are repeating every two minutes. I have stopped postfix for an hour and restarted. I’ve used ‘ps aux’ to identify and kill every postfix process. I’ve emptied the queue with ‘postsuper -d ALL’. Whatever is happening here, I cannot find a way to kill it, and it has been going on for two days. Any ideas? Thanks in advance!

Can anyone suggest where else I can get support / help with this issue? The error is repeating 720 times a day. Digital Ocean support does not respond only to send an automated email suggesting to post to this community, and there has been no support through the community pages. Are there other places to go to find customer support ? I have searched the Internet for two days trying to find a solution. Is there anyone who works with digitalocean who can at least acknowledge that they have read this request? Please?
