Hi!
Apologize if this question is redundant, but i cannot find any info anywhere...
I'm trying to set up a Postfix smtp server on a azure vm, running Ubuntu, for some testing, but port 25 seems to be blocked somehow.
* I set the ip static during vm setup.
* I have made the Inbound Security rule on port 25 for the nsg.
* i have opened up my iptables on port 25. And tried without iptables.
* i have tried with reverse set up, and without. on several vms in different datacenters.
I still get "No route to host" when telneting to the IP on port 25. When telneting to port 80/443/465 everything is Ok. What am i missing here?
Appreciate any hints. Thanx alot.
Regards
