    Hello,

    I have my cPanel set with Sendgrid.

    And It seems like someone hacked my SMTP server and set it to send spam,

    I found it as soon as it started but still 1k mail were sent.

    Now,

    I am a real cPanel noob, i did applied this in my WHM - prntscr.com/ch3fg5

    And it seems to work, but am not sure.

    This is my standard mail details - prntscr.com/ch438t

    &

    This is the "hacked" mail details - prntscr.com/ch43u9

    Is there anyway to fix it out?

    The setting i applied, are those sufficient?

    It may just be your terminology, but I don't think they hacked your SMTP server. It is far more likely they gained access to an account, since the used an external IP though dovecot.

    As cPanelMichael said, you've basically broken your server and external sources (like Outlook) can no longer send mail.

    You should set email send limits in WHM to prevent massive email dump, as well as the other things on the link that cPanelMichael send you.
