Yes, add custom records (wildcards / spf records etc.) to:
/var/named/chroot/var/named/db.yourdomain.tld.include
Although I'm not sure whether it's necessary I also restart named:
/etc/init.d/named restart
and also, disable and save, then enable and save, the DNS server in the BQ gui.
This works 100% for me and the changes remain in place regardless, even through a
reboot.
