I currently have two gmail addresses. The secondary is added to the primary via the Account and Imports section so I can manage the secondary email address through the primary email address.
When sending mail as the secondary email address (while logged into the primary address), the receiver is seeing a "x on behalf of y" in the from field. How do I remove the "on behalf of" part so it just shows the address that sent the mail, and not that I was using a different account?
Here is the section for: Account and Import -> Send mail as -> edit info

How do I get rid of "On Behalf Of" from my sent Gmail messages?
As can be seen from the above screenshot, there is no "next step" option. Therefore, you cannot specify a SMTP server.
