If you are still using CentOS 7.9, it's time to convert to Alma 8 with the free centos2alma tool by Plesk or Plesk Migrator. Please let us know your experiences or concerns in this thread: CentOS2Alma discussion
After fresh installing Plesk 11 on Debian 6 I had problem with sending emails, so I comment out the line "smtpd_milters" in main.cf. In this case autoreply should working properly?
What exact problem do you have now? Autoresponder only or you cold not send all emails?
Try to switch MTA to Qmail and switch back to Postfix http://kb.parallels.com/en/5801
