Hi,

I'm setting up my domain in DNS manager, which is a great service! One of the things I would like to do is to delegate a subdomain to another nameserver. Adding the proper NS records works fine in DNS manager.

However, this breaks MX and TXT records which are inserted after the NS records. In particular, when using a default MX record (with blank subdomain field), it applies to the subdomain referenced by the previous NS record instead of base domain @.

I tried specifying @ for MX subdomain, but DNS manager rejects it. I then tried putting "mydomain.com." for fully specified domain, but DNS manager strips off the required trailing "." which means that it now specifies an MX record for "mydomain.com.mydomain.com." obviously not what is needed.

So there appears to be no way to specify both delegated NS records and default MX records in the same zone file.

Suggested fix: allow "@" to be a valid subdomain specifier in MX records.

BTW, using "@" for the name in the TXT records is accepted, and seems to work as expected.

Thanks for the great service!

I've fixed this in the zone rendering code by using "@" instead of <blank>. Can you verify that this fixes the problem?

Thanks,

I checked my case, and a bunch of other scenarios. They all look fine. Rendering "@" instead of <blank> in the zone file seems to fix the problem.

Also nice to see updates every 15 minutes instead of hourly.

Thanks!!
