<span>Named uses the NS records for the zone to find the addresses of the secondary servers to send the NOTIFY messages to. Both primary and secondary servers do this by default. The nameserver listed in the SOA record MNAME field is excluded this process.
Ensure you have address record for all your nameservers.</span><br>
<span></span><br>
<span>If a secondary is not listed in the NS RRset then you can use also-notify as Anand said.</span><br>
