Under the settings tab, I have added a second email address I own via the “check mail from other accounts”. That is all working fine – emails are coming in to the inbox. However I can’t send as/reply via that email address.
When I go to add it in the “send mail as” option, I type in the email address, then click next, and get the following error message:
You must send through (my domain) SMTP servers when you send as (my email address). However, this functionality is not available for your account. Please contact your domain administrator for more information.
I have contacted the hosting company for my domain, and they have checked the situation and said it’s nothing at fault their end and that is is to do with the Gmail interface so can’t assist.
2. Go Apps > Google Apps > Gmail > Advanced setting.
3. Search for “Allow per-user outbound gateways” and enable this setting.
4. Save changes.
It may take up to an hour for the changes made in the Admin console to be reflected in the user accounts so please allow some time to pass and try again if you get the same error.
