    Hi,

    I have a user on my VPS receiving regularly forged emails. When they phone call back the true sender, he deny sending any emails.

    I tired it myself, I used emkei.cz/ and forged my self and it worked. I tried to send forged email to my Gmail account, it didn't worked, considered spam and just filtered.

    I tried it after turning on "Allow DKIM verification for incoming messages" and "Reject DKIM failures" and restart exim. Still same results, is there a way to block those incoming forged emails ?

    Just want to add that Boxtrapper and SpamAssassin are turned on.

    Thank you

    Hello,

    Have you considered enabling the Greylisting feature in "WHM >> Email >> Greylisting"? Per it's description:

    It's documented at:

    Greylisting - Documentation - cPanel Documentation

    Thank you.

    Thanks. I'm experimenting this feature. Not so promising as most forged emails are recognized by the mail client and server. I think there no solution for spear phishing.

    It worked on Gmail and outlook accounts too, if you use a recognized email address.
