How to send emails from my domain from the gmail web client?
I'm trying to send emails from the gmail web client with firstname.lastname@example.org as sender.
Currently I have PostFix installed which is forwarding emails send to anything @mydomain.com to my gmail inbox. And if I send mail from the command line, they get sent using my gmail account. (And with email@example.com as sender)
I want the last bit the other way around, I want to add firstname.lastname@example.org as an alias in gmail so I can select it as sender.
99% of the google hits are to set up postfix to use the gmail smtp server, so I cannot find what I'm looking for.
I'm open to getting rid of my current postfix installation if another program will serve me better.
