G-Suite – Always Use Group Address in Replies

Groups in the Gmail contact manager are not the same than Google Groups.

The groups in the Gmail contact manager will always change the group name to the list of the group members email addresses, by the other hand, Google Groups will always show the email address when it's included in TO or CC.

Ask you domain administrator to create a group in the admin.google.com or if you have access to Google Groups for Business for your domain and are allowed to do so, create a group. To do so:

1. Go to http://groups.google.com/a/yourdomain.com
2. Click on Create group
3. Follow the on screen instructions.

This masking happens as Google Groups forward incoming messages: In case the sender has strict email delivery settings, Google needs to show that it redirected the message (and thereby became the new sender of the message). Otherwise, clients would reject it as being spoofed.

Hitting replying to those messages should still work as the reply-to address gets correctly set.

From the product forums:

This is to prevent rejections of messages from senders whose domains have a 'reject' DMARC policy. The change involves re-writing the From address so that it no longer points to the original sender. In doing so, the received messages display the sender as ‘User Name’ via .
