Hello everyone,

I am facing a curious problem with my Plesk server that I hope you can help me to solve. When trying to send notification emails from Plesk to the same email address configured for notifications (admin@[CENSORED DOMAIN]), the sending is failing.

Here is an extract of the logs I was able to obtain, where I have censored sensitive information:

If I send myself the mail to my own address there is no problem, but if from the system notifications.
