Hii all,
I have a problem with DNS resolution for one specific domain. Email are sent/received fine for all other domains.
However i found that the remote domain on which the email delivery is failing is because my internal dns give request time out when i nslookup to that domain. However when i use 8.88.8 as dns server it gets resolved.
What configuration should i do on my local dns to resolve this issue. Add the record manually in dns or some server need restart.
Because as i remember the mails to that specific domain were working fine until today....
Thanks
