    Hey Guys,

    Does anyone know of an exim filter (or other solution) that I can add to check the from address of e-mail being dispatched and black-holing / rejecting mail sending from domains that don't exist on the server ?

    Hello :)

    You could try enforcing SPF checking by enabling the following option under "ACL Options" via "WHM >> Service Configuration >> Exim Configuration Manager":

    "Reject SPF failures"

    This will reject mail at SMTP time if the sender fails SPF checks.

    Thank you.

    Doesn't that also affect in-bound messages ?

    does this solution applies on non-existing email accounts.

    I mean there is a valid domain but spammers creates fake account via script on the website, will this be applicable on existing email accounts as well ?

    Could you verify which solution from the URL in my last response you are referring to?

    Thank you.
