If that is not the case then you can just set spf record of your mailserver known as MX record in your dns server. And that will stop other servers from using your domain's email.

Hi,

Surely the spammer took you an user account and he is masquerading your compromised account so you can't detect the source account, you need to change that account's password and to find it you have to search in your maillogs.

I am not certain if you server has just a backdoor installed but first of all i will proceed with the above explained.

Good look guys!

I'm not sure how to help you guys with this. Have you thought about asking on the spamdyke or spamassassin mailing lists?

    Dear Eric,

    Recently I have observed all of my servers getting
    spoofed display name spam mail. Which mean someone spoofing my
    user display name only and sending lots of spam which my user
    thinking came from their boss or someone important in the
    organization. Is there any rule which can stop spoof
    display name spam in spamassasine?
