Como posso usar o CNAME no Bind corretamente?

Question

Sou novo no Bind / DNS e quero apontar / mapear SMTP, webmail e IMAP para meu domínio, mas um check-in nslookup está falhando. Como posso nslookup SMTP desta maneira?

O erro que recebo é: smtp.stylez24.com: NXDOMAIN

No meu arquivo de zona direta eu tenho isso, o que me permite nslookup meu domínio mas não SMTP:
