how to open 25 port without requesting the cloud provider service team for open port
need help for open port 25 in digital ocean, linode cloud, azure etc.
 
you cant as they block it with an external firewall that you dont have access to.
so the only way is to ask the provider to allow traffic on port 25.

Can I open port using firewall in server??
 
no as its blocked via a hardware firewall on the network, not software on your system as that would be too easy to circumvent.
