Hi,
I have been running my own exchange server without any issues, my isp was providing me a static ip address.
2 days ago I changed isp & they only offer dynamic ip, I signed up for Zoneedit & everything seems be running fines web servers & I can receive email.
When i try send email I get the following error
Remote Server at gmail.com (2607:f8b0:4002:c03::1a) returned '400 4.4.7 Message delayed'
22/07/2015 12:40:04 AM - Remote Server at gmail.com (2607:f8b0:4002:c03::1a) returned '441 4.4.1 Error encountered while communicating with primary target IP address: "Failed to connect. Winsock error code: 10051, Win32 error code: 10051." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts. The last endpoint attempted was 2607:f8b0:4002:c03::1a:25'

Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts. The last endpoint attempted was 118.333.101.190:25'
I checked with my isp and port 25 is not blocked.
I am not sure what I am missing here, this is my first DDNS setup
I have attached my setup in zoneedit control panel
Any help would be great.
