Runbox SPF Question
I have a domain with MX records set up to a Runbox account.
I also have this SPF record for the domain:
v=spf1 redirect=spf.runbox.com
I would like to be able to also send e-mails from an e-mail account from another provider (posteo.de), and would want to amend that existing SPF record.
As the Runbox SPF is a "redirect" how would adding posteo.de to that record work?
Could that be changed to "include" instead without any problems?
