I am a certified Quality Engineer, and as such would point out that the software installer is a feature of SME server that at present is not working well on several machines. Thus we should be free to discuss that feature of SME server in the forum. Now we can discuss if the feature is working to specification, and if the email notifications are part of a different feature of SME Server, and if the emails are from several bugs, or are a virus, or our own user mods. BUT it is not within the power of the average user to determine if the unwanted behavior of the Software Updater and Update Notifier are the same bug as was reported many months ago, or even are bugs! Just because something is not working to my liking does not make it a bug!
Many times I've learned that a tiny change I made in one area has had unintended consequences in another! But they are NOT bugs, just unintended consequences! Like putting salt in your coffee instead of sugar. I don't ask my wife to make fresh coffee if I'm the one who put in the salt! Why lumber the bug team when users want to discuss a behavior?
Remember, our Microsoft machines freeze up at least twice a month running updates, and perhaps SME server is SUPPOSED to install those updates automatically! How would we know?
