fraud mail RRS feed

  • Question

  • Hi,

    one of my recipient which id is in hotmail.com is clamming that he has received mail from our domain senders. While there is no such log in our domain for that particular mail.

    Once i analyzed the message header we came to know it is originated from other source through fake mailer or other means. In message header spf is fail. Our mail server is hosted office 365 and spf record is maintained for our domain.

    My question is that how hotmail allow such type of fail whose spf record is fail? How we should get protected from such type of mail.?
