Reject Mails where mail from domain is receipient domain

Ulrich C. Thiess

Is it possible to mark e-mail domains as internal? Many spammers use the recipient domain as the sender domain. Such e-mails can still be rejected during transmission.

    Ulrich,

    can you explain what you are trying to achieve? in order to make sure that email are only sent from the correct owner (so the server) you should use:

    • Proper RDNS record
    • SPF record
    • DKIM record

    Once you have configured them and your receiver uses strict email control (by checking those records) spoofing is prevented.
