What DNS information can I add or change to improve the DNS record for my domain name (tjrobinson.net)? I use it to host a basic website and for my email. ZoneEdit host my DNS records.

Ideas so far

  • Set up SPF record
  • Add DomainKeys support
  • Add Sender-ID support
  • Fix the warnings listed by ZoneCheck
  • Fix the errors listed by DNSQueries

"Improve"? What, are you competing for some sort of prize? What is actually wrong with your zone? – womble Nov 16 '09 at 13:17

Well there are the above DNS check sites giving errors and warnings - what's wrong with investigating and fixing these? What's wrong with improvement? – tjrobinson Nov 16 '09 at 13:26

Cost/benefit, unintended consequences, and having better things to do with limited time all immediately come to mind. – womble Nov 16 '09 at 13:28
I suggest adding some bling to your website. bit.ly/3vJyu9 – duffbeer703 Nov 16 '09 at 13:41

@womble Fair and valid points, but reducing the likelihood of emails from my domain being marked as spam is worth the time/risk for me. Maybe the other apparent problems don't need fixing, but I don't see the harm in investigating, assuming I have the time to do so. – tjrobinson Nov 16 '09 at 13:45

Well, many choices. If you think SPF helps, go for it. DomainKeys and SPF are all origin controlled, though, so it won't result in less spam, it will just help prevent spammers from sending mail impersonating your domain.

If you are getting warnings from something, what are they? Fixing ones caused by queries is probably a good thing, but many tools artificially warn about things that the tool author thought important, but in reality are not so critical.

Also consider DNSSEC, and adding your KSK to http://dlv.isc.org/
