SharePoint 2016 Outbound Email – SharePoint Stack Exchange

SharePoint 2016 email notifications does not work. I followed all the steps in this article and successfully configured everything. When I use telnet I can send emails with the same settings, but I dont get alerts from list changes or workflow emails (workflow completes without an error).

Additional Info: I am the site admin, and I have enabled alerts for all the changes on a list, but I do not get any, workflow emails either. I also tried this script, it also returns false. (Telnet works with the same settings)

I really appreciate any help on how to resolve this issue. Thanks in advance!
