Yahoo Mail (email) DNS Server Out Of Date Problems
I don't expect this to be solved soon but some of Yahoo's DNS servers are out of whack. I changed the IPs of some nameservers of some domains and now most Yahoo users can't e-mail to those domains!
As you can see below by the "No MX or A records for mychangedomain.com", now Yahoo's DNS/mailserver DNS cache is wrong. You would think they would at least have cached the old incorrect records, but instead for some reason their DNS cache has no entry and doesn't seem to want to update itself. Hotmail and Gmail all work fine, and some Yahoo users (probably on different nodes with different DNS) are able to e-mail me. These DNS changes were now done over 2 months ago so it's not simply a matter of slow propagation time to Yahoo DNS Servers.
I'm sure that I'm not the only one, other sysadmins who have changed nameservers IPs may have noticed this. Basically when you send an e-mail to the affected domains you'll get a bounceback like below (it may take minutes, hours or days to get the bounceback).
This is a real annoyance since many people use Yahoo mail.
I actually contacted them about it and nothing was done but I did receive some sort of template/automated response that the issue was forwarded and escalated. I never heard anything further for days and then I sent followup e-mails and not only were they ignored but suddenly my Yahoo mail account was inaccessible.
