Our company is Company1, SMTP address is @Dominio1.com
We need that other company "Company2" (SMTP Address @Dominio2.com) can send mails as Company1. For example..
User User2Company@dominio2.com sends mail tousuario10@hotmail.com, but
usuario10@hotmail.com must see Direccion1@Dominio1.com as remitent.
Important is that we (Company1) can manage these remitents and only allow some of them
Is it possible??
