Hi Mustapah,

That's a bounce, "Delivery expired (message too old)" means the delivery system has given up trying to deliver the message. Obviously the remote host does not listen on connections on port 25 (Connection refused'), could also be a firewall inbetween.

Hope that helps,

Andreas

Can u confirm this problem are from firewall problem or mis configuration mail server
