We are a small resort in Phuket, and we went on the advice of our vender over to Zimbra, and since being set up we have had nothing but problems,
Everytime a mail is sent out of the Network (....@infiniteluxury.com - to - firstname.lastname@example.org) the mail returns with the same error "undelivered mail returned to sender",
Yet when sent from ...@infiniteluxury.con - to- ...@infiniteluxury.com there is no errors.
What could be causing this issue and how can we fix?
