Hi There!
In the past when we have moved domains to other providers, that previously were using xtra for backup email queue, we find that xtra don't remove those stale or out of date records from ALL thier dns servers causing intermittent email delivery issues.
Our experiences with the helpdesk have been frustrating to say the least with most if not all of the people we have spoken to, not even understanding what we are saying.
Anyone senior from the DNS team lurking here that would be willing to be contacted by us to try and resolve outstanding issues, or is there a secret code I can enter on the phone system to get to the senior engineers?
