Do I need Exchange Server for SMTP only
I have a Web based application, through which i intend to send an email notifications to the users . I have put a IIS SMTP role on Windows 2016 Standard edition .
Do i need anything else apart from the SMTP server, like Exchange server for sending Emails. Again for clarification I only need to send Emails to the users and I am not suppose to receive emails through it.
note: we have already Exchange 2016 configured in our environment
Due to this thread related to sending emails from IIS SMTP rather than Exchange server. So, I will remove the "office-exchange-server-mailflow" from this thread.
If you want to relay emails from Exchange server, this article will be useful to you: Allow anonymous relay on Exchange servers
Implementing Exchange Server just to send email from your website isn't worthy. I recommend you to subscribe to exchange online and use that to send email from your application.

ok, my question is can IIS smtp send mails direct to internet without exchange server ?
Technically speaking, you can install SMTP service in IIS and send emails, but that is not the best practice. Mostly your emails will reach in SPAM or undelivered. If you need your application to send email, subscribe to exchange online is a cost effective option. But be noted that if you are planning to do bulk emails, it will not help you, you need to use bulk email services such as https://mailchimp.com/en-gb/
Hi there,
Yes, it is possible. In order to send e-mail from an ASP.NET Web application, you must have the Simple Mail Transfer Protocol (SMTP) service of Internet Information Services (IIS) installed and configured on your server. The IIS SMTP service is a simple component for forwarding e-mail messages to an SMTP server for delivery.
