Sender Policy Framework

Answer to the question from the area: adoption and introduction


My message does not arrive at Hotmail, not even in the Spam folder. Why?

This is because Hotmail uses the SenderID as input into the reputation system. So messages that pass or fail their SenderID checks get a different reputation. The first thing you should do is check that your SPF record is correct and up-to-date. Once you are sure of your data, you can try again to send through another provider. This is because it appears that the reputation system uses a combination of the domain reputation and the reputation of the sending IP address. This will be discussed in more detail in these mailing list threads:
