    Hey guys, I would like to know if, and possibly how, it is possible to block incoming mails from owned domains, which are only sending/receiving on the server itself, so that I can "easily" filter away those spam mails at least.

    Most occurrences of this type of spam usually sends a mail with the "sender" as the receiver. I am hoping that cPanel is capable of differentiating between if the mail came from an external source. Thanks for any assistance provided in advance, I am not very experienced in the advanced settings department but if you can point me in the right direction I can probably manage.

    Best regards,
    René.

    Hello,

    You could enable the following option in "WHM Home » Service Configuration » Exim Configuration Manager" under the "ACL Options" tab to help prevent these types of emails:

    "Reject SPF failures"

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

    Thank you.

    Does this option only reject the domains with SPF setup (hard fail) or does it also reject soft failures?
