根据谷歌的说法,

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.

我添加了SPF和DKIM记录.查看原始电子邮件时,它显示已通过.

Received-SPF: pass
Authentication-Results: mx.google.com; spf=pass …; dkim=pass …

有任何想法吗？
