I wanted to setup an account in my Gmail and I was not sure what my SMTP server on yyy.com was so How to find it out .
Step 1 : Setup the Telnet Client
To do that go to control panel click on programs and then click on add or remove windows features
Make sure the Telnet client is checked
Now Open command prompt and type “ nslookup “
Type in the following
which specifies mail server
Then type in the server you want to ping here i use “gmail.com.” .Use a “.” at the end.
Here it goes the mail Exchange servers Installed at gmail.com
You can see a value called preference which specifies which server is favourable. Lower the value more favourable it is .
I can use the port 25 and TLS settings on my Gmail to setup a secure Network .
