I created a Group in G Suite and added a number of accounts to it. I want people who are members of the group to be able to send emails as that groups email address but it doesn't seem like that's possible.
What I had thought would work was, in Gmail, going to "Settings" -> "Accounts" -> "Send mail as" and then clicking on "Add another email address". The problem with that is that it's asking for SMTP login info. It correctly deduced that aspmx2.googlemail.com is the SMTP Server we'd want to use but as for the username or password... what would that be?
