Per ripristinarlo basta fare così:

My findings are similar to the other answers here, but it seems I needed to add a few steps (under Microsoft Windows Server 2022 Standard):

By default, I can enable SMTP and listen for connections, but when I attempt to send email to its port, the SMTP service crashes. Also, when I attempt to access Properties of [SMTP Virtual Server #1], IIS 6.0 Manager pops up this Snapin Error:

MMC has detected an error in a snap-in. It is recommended that you shut down and restart MMC.
Here is the procedure that worked for me:

1. Stop the Simple Mail Transfer Protocol (SMTP) service.
2. Stop the IIS Admin Service service.
3. Edit (privileged session) C:\Windows\System32\inetsrv\MetaBase.xml.
4. Under <IIsSmtpServer Location ="/LM/SmtpSvc/1", set RelayIpList="" as described in Andrew's answer, and save the file.
5. Start the Simple Mail Transfer Protocol (SMTP) service
6. Important: Now, run IIS 6.0 Manager, right-click [SMTP Virtual Server #1], click Properties, open the Access tab, click the Connection... button and click OK and then do the same with the Relay... button.
7. Now click OK to close the [SMTP Virtual Server #1] window.

The preceding updates your MetaBase.xml file and causes SMTP to function correctly.
