Issue My Plesk is sending SPAM

[Marcio Nunes]

Hello,
I cannot locate where the problem is, but my Plesk server is sending SPAM through a domain that does not have an active email service.
My server is not allowed to send email by PHP script.

I changed all the passwords and passed ImunifyAV and it's all clean.

It is the first time that I have not been able to solve a problem of this type.

Help will be of great help!

First step is to look into /var/log/maillog and isolate a single case, then carefully examine where the mail originates. Normally you'll find at least a user name that is submitting it to the mail queue.
