What is the meaning of a "redirect=" modifier in an SPF record?

The "redirect=" modifier transfers responsibility for the SPF record to the specified domain.

  1. An SPF record may contain only one "redirect=" clause.
  2. A "redirect=" modifier is not evaluated unless the end of the SPF record is reached and nothing was matched. In particular, if an "all"mechanism exists, then "redirect=" is never evaluated.
  3. An "include:" mechanism causes the referenced domain's SPF record to be inserted into the current domain's record.
  4. A "redirect=" modifier completely transfers responsibility to the specified domain, and never comes back.
