    Hi,

    I am facing the same issue as mentioned at below thread. I tried to reply on this thread but it is not allowing me to reply to this thread. So I have opened a new thread.

    http://forums.cpanel.net/f43/spoofing-mail-my-server-153769.html

    " Hello people,

    I have a problem with some of my clients. I have some servers and some of my clients send mail authenticating with their mails but using other accounts (out of my clients) as sender, for example:

    Client: clientone.com
    Authenticate Email: admin@clientone.com
    Sender Email: marketing@anydomain.com

    How could I do to take control about mails which go out from my server or even go in from accounts of my clients with characteristics above?

    Thank you for your help. "

    Can anyone please help how can I stop this on server.


    Thanks

    You can enable Spamassassin outbound email scanning. If the from header in the email is external, and different than the actual sender Spamd should mark it as spam and reject.

    You need to modify exim advanced settings to accomplish this.
    Basically need to put a check that if sender domain is not in local domain file then it should be rejected.

    This will do exactly what you want to . This isn't officially cpanel supported though . But would work. Search exim forums as well.
