I am trying to move emails from my Gsuite gmail account with custom domain (ex. email@example.com) to my new gmail account (ex. firstname.lastname@example.org). I am setting POP3 forwarding with deleting messages from the original account. When I am asked on new account to insert my POP3 server address, from which to import email, what will it be? I have tried mail.example.com, webmail.example.com, pop3.example.com, pop.example.com, pop.gmail.com. It simply doesn't work with any of these. Also, I have 2 step authentication active on the Gsuite account example.com (I do not know if this can make further issues).
