GMAIL Alias Email is bouncing back

I used Homestead as a GMAIL reseller and am not able to send email messages using my GMAIL Alias accounts set up in my GMAIL admin console. Homestead is flagging the alias accounts and bouncing the messages back (error message below). I have a another GMAIL business account where the Alias emails are used minus Homestead as the reseller and this is not an issue. Is Homestead not able to recognize the GMAIL Alias account functionality that is directly tied to the domain of the GMAIL business account? 

The error message received is as follows:
