Il s’agit évidement d’un SPAM mais mon pb est qu’il est signé d’une adresse sur mon domaine.
Mon serveur de mail est un DEBIAN 10/POSTFIX,DOVECOT
D’après ce test https://mxtoolbox.com/SuperTool.aspx?action=smtp%3Amail.webologix.com&run=toolpage mon serveur n’est pas en open relay.
Comment fait on pour signer des mails avec une adresse à moi ?
