With my postfix I cannot send any message to an host that for this
example I called xyz.info

this is the error in maillog
Host or domain name not found. Name service error for name=xyz.info
type=A: Host not found

If in a shell I digit the following commands this is what I receive
back


host -t mx xyz.info
xyz.info mail is handled by 1 mx.xyz.info

nslookup xyz.info
Server: 192.168.123.75
Address: 192.168.123.75#53

Non-authoritative answer:
*** Can't find xyz.info: No answer


ping xyz.info
ping: unknown host xyz.info

Any idea

Thank you

Sounds like either mx.xyz.info does not have an 'A' record in DNS,
or your system can't reach their DNS.
