The domain's SPF record is like: v=spf1 a:primary-mx a:forwarding-mx -all

This configuration only allows mail to be sent for the domain from the specified hosts primary-mx and forwarding-mx - It does nothing for mail from other domains which may be forwarded through the host forwarding-mx. For forwarded mail to be correctly received, the SMTP envelope must be rewritten.

 

perl -le "print unpack'N', pack'B32', '00000000000000000000001011010111'"
