Yes indeed! F5 can send alerts of any kind. However, what determines the DELIVERY or whether authentication is required or not, is the mail server receiving the alert. So, F5 doesn't care how you send the alert ( authenticated or not ), it is the receiving mail server that determines how he wants the mail to arrive which then determines the mode in which F5 sends it ( authenticated or unauthenticated )

So I’m thinking the server needs to be an open relay? But I don’t think most people are using those in their enterprise networks.
