I have had problems with setting up DNS for myself and I need it to be authoritative. I have my domains registered with Godaddy and they do not support for domains not hosted on their servers. I have been using their DNS without big problems, except that I'm not getting proper results with regards to email. I've got a pretty bad problem with spam. I now have two servers, each with a different company.
Will that then solve the problems with PTR, DKIM and DMARC? I also particularly hate the web GUI that Godaddy uses and it's SOA record is much too long timewise. Should I set it up with just one of my servers or both? One is in Los Angeles and the other is in Miami. Do I need to use a different one to cover the other server or can I just use the same one to cover the email stuff like DKIM and DMARC? Since I'm having problems from the ground up, this seems like a good idea to start at. I'm also seeing conflicting advice on whether I should use multiple A records for subdomains, like www. smtp. etc. or CNAME. Plus it's not clear to me whether to use records like _smtp.tcp or not bother with those. I have spent a lot of time reading pages on all of these subjects but I have yet to find a complete example of all DNS records for a site. Would anyone care to share one with me? Thanks, Chris Bennett
