Summary:

Share page email has the from address of the mail server, but reply goes to the user.

Can from address be changed to reflect the address of the user. As this can be confusing for the customer.

2. Go to a page, and share this page by the button on the upper right.
3. Check your e-mail and look for the from address of this email to see if is no_reply@something.com
4. Reply to the e-mail, and see that it goes the user.
