Hi Hi TPG Comm,
Hopefuly I can get some help. One of my senders frequently gets the attached email failure error when trying to email me at my @TPG.com.au address. They can send from their @Me.com address successfully and I receive emails successfully from all other senders.
I suspect an issue with their domain that is failing? Is that correct?
Thanks
Nat
