There are 2 parts in SPF: - Create the record - Check the record and filter
I was stating that the second part is ok if you know that no forwarded email streams reach your server (or if you have identified them and switched of the check there). The first part, creating the record, is a matter of opinion (and there are some strong ones around...). Met vriendelijke groet, David Hofstee Deliverability Management MailPlus B.V.
