Hello everyone! We add editable TXT record.
If you want to add other mail server to SPF, you set "_spf" to HOST, and TYPE is "TXT". When we find out "_spf", we add "include:_spf.yourdomain".
Other, you want to add DKIM, you set "@" or other to HOST, and TYPE is "TXT".
Caution! We do not check your TXT record format.
