Removing Via link by Gmail
|Knowledge Article Number||000175959|
|Description||When customer is using Gmail and sends emails through Salesforce, recipients see the From field with the customer's email address and with a via link indicating where the email was sent as detailed in the image below.
This is how Gmail handles emails for transparency purposes. Please note that configuring this is beyond the scope of Salesforce Support. However, if you wish to remove the Via link, click this then scroll down to:
"I'm a sender and I don't want my recipients to see the "via" link. What can I do?".
Note that it points to number 2 (SPF record). This means that you will need to publish an SPF record that covers the Salesforce sending MTAs. See http://www.openspf.org/
