Help !!!

I have purchased a domain for a family member.
I set the domain name servers.

I setup the fastmail account for them.
Fastmail's automated setup for Domains indicates all is set properly.

The email account can receive emails with no problem.

I sent one email from the new account and it worked.
But after that first email, no other email makes it to the named recipient including the very first one.

Oddly the emails show up okay in the sent folder.
I can send an email from the account right back to the account with no problem.

Neither sender nor recipient has a black list, a domain block, nothing is in anyone's spam folder, there are no bounce messages. It just never makes it past Fastmail's system out into the internet.

Cannot even send to a mail tester.

Something is not set right, but I cannot figure out what.

Domain name registrar says it is Fastmail's problem to figure out.

I have put in a ticket to Fastmail, but no response yet.

Anyone know what is happening here ???

Help please.
