We have a redirection service at Tierranet.com which has been working very well for over 10 years. It has been working well with TPG as well until recently TPG has started to reject one address, firstname.lastname@example.org with an error of Client host rejected. I have had Tierranet look into it and they confirmed that it is not their end. Also all the other redirected addresses are NOT being rejected.
Extensive testing from other PC's using Gmail, Yahoo, Hotmail and Westnet have shown that only 3 out of 5 emails to email@example.com are getting through.
We use the redirection service so we can keep our own domain, beverleybb.com, and all redirected addresses go to firstname.lastname@example.org. It also means we can change NBN suppliers without changing all our email addreses.
Could it be looked at as it is a serious problem to us.
We chased this with our Postmaster and they'd like to get additional details for the ongoing investigation.
Shoot me a private message with the screenshot of the Error or Bounce Message and t he latest email that was not forwarded.
Has there been any progress with this problem since we sent an example of the problem
