    I discovered at WHM >> Main >> Email >> View Sent Summary that remote user is sending over 400 Successful emails and over 300.000 Failures emails in last 2 days. I'm wonder how this could possible or how can I find the cause of this issue? Thanks !

    In the cPanel of the domain, Default Email address, what is this set to? Not sure if this is helpful at all but worth checking.

    The settings are correct there.

    Where you see -remote- on the WHM >> Main >> Email >> View Sent Summary screen, click it. The result should be helpful in giving you some idea whats going on I think.

    How are the messages being sent exactly? There is a path where I can find a script that send those emails? or the spammer use valid SMTP credentials to send this? How to stop spam email's being sent ?

    Hello,

    The first posted log shows the user was a delivery to the machine from what it appears. The second indicates it was "Authentication: localuser" so a local user authenticating.

    If you are having the same issue, please submit a ticket to us and provide some of the logs in question for us to go over the logs.

    Tickets can be submitted in WHM > Support Center > Contact cPanel or using the link in my signature. Please post the ticket number here afterward so we can track the issue for future reference purposes.

    Thanks!
