What software/package required on a new Windows machine (say Win10) to send email. My understanding is that it needs SMTP client kind of software installed to communicate with an SMTP server to able to send email. I know we can use telnet to an SMTP server on port 25 and send email. But what is not clear to me how an application will send email - does it need integration with SMTP client on that machine to communicate with SMTP server?
I think I have problem with basic concept here? Anybody can help?
