Your lookup is incorrect. The domain in question is server.cointalk.com, not nginx-at-server.cointalk.com. The latter is the sender e-mail address (localpart-at-domain).
The cause of the problem, however, is that there is no A record for server.cointalk.com:
me-at-localhost:~ $ host server.cointalk.com Host server.cointalk.com not found: 3(NXDOMAIN)
Postfix rejects the mail because it cannot resolve the sender domain.
