I am using the hosted service from phpList and we are facing an issue. We get all our contacts under the following email domain “t-online.de” automatically bounced. Do you have any idea why t-online.de is refusing our email deliveries? Is this kind of error usual with phpList?
But in general what should we do if we receive reports of no-delivery (bounced) messages to people having their email from one specific domain after sending a campaign? How can we correct this situation?
I am still asking before I am still studying if we should have our own server (outside of the hosted service) or not… so I would like to study ahead how this situation could be fixed, in order to take a good decision.
