We have a developer creating a new website on a new server (Win2012r2) and the developer wants to allow website visitors to send email to the webmaster via a submit button. What needs to be enabled on our web server to make this happen? The web server sits in the DMZ, and this function will be used by external people.
With our current Win2008r2sp1 web server, SMTP is not installed and when you click on a link on a page to send mail to the webmaster, it uses whatever mail client is installed on the local machine. That is the same behavior I want on the new server, but it was setup by someone who is no longer here. The current developer is saying I need to open port 25, but I don't think that is necessary.
