    Hi you wont be able to additional MailFrom addresses if you are using the default limits.

    You would need to open a ticket to raise those limits.

    Hi Luca,

    In order to be able to Add custom Mail From addresses for your custom domain you must first increase your sending limits. To do this you must meet requirements (see article in step#8 below) and submit support request.
