Reject Mails where mail from domain is receipient domain

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.

Yes you are right. The SPF record prevents e-mail from being accepted with the sender's own domain.

Sometimes it is good to think about it again.
