    Hi,

    You are defining SMTP host smtp.office365.com but connected instead to dedihost1.webleaders.gr. I assume your domain in question is siamo.gr.

    TLS was created to deal with this man-in-the-middle attacks, your hosting is redirecting SMTP requests to own servers for some reason, talk to them to fix this.
