We just moved our website to a hosted server - but are keeping Exchange 2003 to manage our mail for the meantime. The DNS change has taken effect, but I think there maybe something wrong with the MX records.
mail.mydomain.com A Points to x.x.x.x which is the destination of the exchange server And mydomain.com MX Points to mail.mydomain.com
I updated the MX records after changing the domain DNS, but my understanding is that the MX record change time is typically the TTL (1 hour in my case) however, it's been several hours and I'm still bouncing mail.
Can someone give me their experiences with record changes and TTL times? Are they usually consistent?
Update: - from farseeker and mrdennys answers, it's just a slow update on the DNS cache. I hope it doesn't take 72 hours - but as long as the configuration is right, then it takes as long as it takes. I'll keep checking every 10 minutes and report the results. Thanks
This is the Non Delivery Report:
Delivery to the following recipient failed permanently: email@example.com Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 sorry, no mailbox here by that name. (#5.7.17) (state 14).
This is my first experience with Plesk. I thought I was modifying my DNS records but I think it may be having no effect.
Latest Update: - Alright, mail.mydomain.com is now pointing to my mail exchange server, but emails are still getting the same NDR. Are there other variables to consider, such as ports - since the emails are being routed through an external server?
