    Hello,

    Noticed that there are lots of mails being sent from user@hostname.com (this is the user when it gets created when we Add hosting of domain name in cPanel)

    Any Idea how to disable spamming from such users?

    Well, depends what kind of scripts those users use to send mail. You can disable mail() function in PHP, so will have to use SMTP with authentication. Or better search and block those scripts, which generate spam. Since this could be also "good" emails, each case should be investigated separately.

    I'm sorry, your query is unclear to me.

    System emails, for example quota or email box full emails, are sent to the system user. user @host.servername.com and are forwarded to that users real, Contact email address. user @host.servername.com is not a "real" email address.

    ConfigServer blog has a post on this located here you might find interesting:

    Well, we'd have to see some of the emails I think to be able to give you proper direction.

    User mileshig is the cPanel user. He can't send emails out on "his" own. His scripts could, as Anton mentions above. For mileshig to send email, he'd have to create an actual email account, which by your image, he does not have right now.

    Depending on the settings I mentioned previously, a spammer could send emails to anyname at mileshig's domain.com

    I can add to this:

    Let's say Bob's email address was hijacked and now bob@somedomain.ltd sends spam, using outlook (or any other email client) through SMTP.

    How does one stop all outgoing mail for a certain user, or domain?
