We want to start sending some emails from the assigned contact owners. We are using personalization fields Owning User Name & Email for both the sending from and replying to information. During testing, emails sent to our company email addresses are getting soft bounces with this information, smtp;550 Rejected by header based Anti-Spoofing policy.
Emails being sent to gmail and yahoo test accounts are working fine. Emails sent using our default email address customerservice@... never soft bounce when tested on company email addresses. Any thoughts as to why this might happen? I'm thinking of a larger test to some actual customers to see what the bounce rate looks like.
