We’re trialling CF and have run into an issue with email delivery.
We also use a third party spam engine and since moving the domain over to CF, every single inbound email is being flagged as spam - the reason is that the subject and other header items are being stripped en-route.
Route is Sender → CF → SpamEngine → Recipient
When we remove the domain from CF (take CF out of the equation), all is ok again.
Is there something that we need to do to ensure email is delivered correctly ?
