Hi all,

I was working on a batch file to make it run ipconfig /all create a text
file with the result and email it to me.
While working on it I discovered that I was able to use our SMTP engine
from outside without any authentication, like this:

commail.exe -from=MyEmail1@xxxxxxxxxxxxxxx

Is this normal?

How can I secure it so it would only be used by authorized personels.
