I have allowed port tcp port 995 from Azure rules. But still the port cannot be accessed I guess. OS firewalls also has been disabled.
When trying to use Mailu the following error occurs:
Error starting userland proxy: listen tcp4 xx.xx.xxx.xxx:995: bind: cannot assign requested address
Talnet check gives this result
root@Monique gmx :/mailu# telnet xx.xx.xxx.xxx 995
Trying xx.xx.xxx.xxx...
telnet: Unable to connect to remote host: Connection refused
I'm new and trying to learn. This is for practicing. Can anyone help?
You can test the port on Azure portal at your VM blade. Enter in your VM Blade, go to the bottom and select "Connection troubleshoot" . On the right panel select Service custom and port 995 then Test. If works you port is open. Otherwise check in the same blade, networking and then if there is a rule for port 995.
Thank you. I will try this.

This is actually a straight forward method and quick. Nice I have remember this feature. sometime i forgot it.
If your NSG rules are correct, and the OS firewall is not blocking requests then generally this would mean that there is nothing listening on that port on the VM. Check that the service you are trying to talk to is running.
You should also check that there is nothing on your network that blocks outbound traffic on that port.
Nothing is listening on that port and I was try to assign Mailu services which was being automatically assigned to the ports when I run the package. But it gives the above error which was shown first. Is this port being blocked by Azure like the port 25? All the outbound traffic has been allowed without any restrictions as it is for testing. So, any possible solutions? The package I'm trying to install is 'Mailu' email server.
If nothing is listening on that port, then it will not work. Your mail service needs to be running and listening on the required port.
How to run the mail service when it fails during the configuration process with an error mentioning that this port cannot be assigned although it is required to run the mail service?
Yeh. Port 25 is blocked. Need to dig a little about the issue. Thank you
