I have been using miab for sometime now and have always had issues with the custom dns component. The mail part is great!
The other day I removed an A record entry and added another A record entry. Strangely the process completed successfully, I usually receive an error which forces me to reload the custom dns page which then shows the updated entry.
Only this time the change has not propagated through dns. Mxtoolbox still shows the old a record.
So I checked the nsd zone files, I can see that the removed A record is still listed in the domain zone file for jbsmith.id.au and also is listed in the zone file for jbsmith.org which is the new entry.
Is it safe to just delete or comment out the entries in the zone file and reload nsd?
