    I have a VPS and my provider is telling me that it is sending thousands of outgoing emails in an hour base on their monitoring system and so they restrict my VPS for outgoing emails.

    My VPS is has CentOS and Cpanel/WHM.

    Exim mainlog only shows that my VPS is sending less than a hundred emails per hour, and my provider said that this may be caused by third party script that sends Outgoing mails directly and bypassing Exim and so Exim does not log this.

    How will I check my VPS on what account or domain that is sending these emails for a specific day and time?

    How will I unblock direct SMTP connections from all scripts on my VPS and should pass through Exim?

    Also, in Home »Security Center »SMTP Restrictions - this is ENABLED already.

    What should i do to determine whose account is sending this numerous emails.

    Hello,

    Firstly, check for open relay: Check an Open Relay .
    If it's open fix it.

    You should also double check exim settings, restore defaults.
    Try updating cpanel version.
