They never asked me for that (UK here). Was up and running with just the basics in minutes. Are you on a list? 😅

They do have a waiting/payment cycle period on their server offering before they’ll open mail ports. Once you qualify, you still need to raise a ticket to ask. That was a bit annoying as my new ISP is stricter with the ports than prior, meaning I had to wait before my relay workaround could send mail.
