I'm using an @d3technologies.com account via google but have an alias for @disguise.one I want to use. I've setup Thunderbird to allow me to actually send and receive using the alias, using the "Manage Identities" function. But depending on the client it still shows the primary email address and not the alias. If the alias does show, it says via d3technologies.com and I don't want it to do that. Can anyone shed some light?
