Cely zonovy soubor je blbe (chybne definovan NS, CNAME smtp a imap nebude fungovat,...)

Za 1. nelíbí se mu, že má jen jeden nameserver, píše, že každá doména (zóna) by neměla mít méně než dva DNS servery.
Za 2. si upravte ten zónový soubor v doméně takto:
@ IN NS domena.cz. změňte na @ IN NS ns.domena.cz.
Přidejte si tam tento záznam: @ IN A 192.168.2.10
Máte také reverzní zónu?
