Hi,
looks like a simple DNS error to me.
In order for mails from -at-server.cointalk.com to be valid, that domain must
exist as A records in DNS.
You could whitelist *.cointalk.com in postfix config, but I suggest fixing
the DNS.
Greets,
Ludi

I'm sorry to bother everyone
Any clue why this is happening from the cointalk.com domain I am locked out
