    Hello,

    I would like a script or a configuration in my cpanel that in case a user sends an email message to more than 10 recipients, this message is automatically frozen and not sent.

    Does anyone know something like this or can you help me?

    Thank you.

    There are 2 settings that might be just what you are looking for :-

    Maximum message recipients (soft limit) (Minimum: 1; Maximum: 100)
    Reject any recipient addresses after this number have been specified for a single message. NOTE: The RFCs specify that SMTP servers should accept at least 100 RCPT commands for a single message.

    And

    Maximum message recipients before disconnect (hard limit) (Minimum: 1; Maximum: 100)
    Disconnect and ratelimit any connection that specifies more than this number of recipients for a single message. NOTE: The RFCs specify that SMTP servers should accept at least 100 RCPT commands for a single message.
