During the setup, I set the name to my domain.tld (excluded the hostname). As well I created a domain when asked during setup of the same domain.tld.

I can send, but get the following on a receive:

Oct 26 17:23:45 wings postfix/lmtp[11182]: 374B8BCC661: to=, relay=none, delay=0, status=bounced (Host or domain name not found. Name service error for name=domain.tld type=A: Host found but no data record of requested type)

What am/did I do wrong?
