    Hi,

    I have allowed limited the number of emails sent through the cPanel server, 30 emails per hour.

    Yet, somebody was able to spam 6 thousand email through the "contact form" of the hosted website on the server in less than 24 hours.

    How can I totally resolve this issue & i can get alert if 100 emails are more sent

    Hi,

    I have exactly same settings but yet again my server was victimized.
    What settings am I missing?

    Kindly check mail report in send.png & mail settings in tweak.png

    Hello,

    The report you provided shows the total amount of email sent over the course of 2 days. You are also showing the max hourly emails set to 50 but if the max hourly emails is set to 50 and they're either not reaching that or reaching it then sending more as soon as it's cleared it's fully possible they could continue to send mail.

    What do you have set for the following two tweak settings?

    Maximum percentage of failed or deferred messages a domain may send per hour
    The maximum percentage of a domain’s outgoing mail that can consist of failed or deferred messages. Once the domain exceeds this percentage, it is temporarily blocked from sending mail.

    - Default 125 %

    - unlimited

    Hello,


    I would leave this setting:
    At its default value - meaning 5 failed deferred messages need to be sent before the system starts counting.

    for:
    This is pretty much up to what you want to set it to - a conservative number like 50% would mean that if a domain sent 20 emails and 10 of them failed or were deferred in one hour, the account would be temporarily blocked from sending mail.


    Thanks!
