I'd like to allow Google Apps and CampaignMonitor (email marketing service) to send emails from my domain.
I've set my TXT records to:
v=spf1 a mx include:_spf.google.com include:cmail1.com ~all
However, all emails sent from Google Apps shows:
Received-SPF: neutral (google.com: 209.85.216.43 is neither permitted nor denied by best guess record for domain of [email protected]) client-ip=209.85.216.43; Authentication-Results: mx.google.com; spf=neutral (google.com: 209.85.216.43 is neither permitted nor denied by best guess record for domain of [email protected]) [email protected]; dkim=pass [email protected]
How can I make my emails SPF "pass" instead of "neutral"?
