When sending emails from Amazon SES, gmail shows "sent via amazonses.com". How do I remove this?
According to Google,
I'm a sender and I don't want my recipients to see the "via" link. What can I do? Gmail checks whether emails are correctly authenticated. If your messages are sent by a bulk mailing vendor or by third-party affiliates, please publish an SPF record2 that includes the IPs of the vendor or affiliates which send your messages and sign your messages with a DKIM3 signature that is associated with your domain.
I have added both SPF and DKIM records. When looking at the original email, it shows both passed.
Authentication-Results: mx.google.com; spf=pass ...; dkim=pass ...
