    Change your passwords and REQUIRE that SMTP and POP3 services are authenticated before use.

    Hello,

    Thanks you very much for your help, but I have already "services are authenticated before use" in my Plesk / setting / mail

    also about the password, you mean the password of my Plesk ??

    I don't know how can someone use my server to send email ????? can you give me an idea or a link to understand that please.

    Really Thanks a lot for your help, I appreciate it.

    First issue is using Plesk..

    Change your passwords would mean every mail account on the server and possibly your control panel passwords too.

    Relaying is different than authorising regular mail sent through your smtp server.
    Relaying should really be turned off. If it's a personal vps you won't need it.
    Maybe you can find regular smtp server authentication settings somewhere else?
