Re: Even to this day...
That's a good idea although I recently had a situation where users were receiving emails from a system I maintain and I could find no evidence that my system had sent it. After looking at the mail headers and finding the sending IP I discovered there was a duplicate of the live VM running right down to the same hostname! It was merrily pulling in data and sending out order updates all on an old copy of its database.
I don't know who spun that server up or why, but you should always beware that some dodgy sysadmin hasn't cloned your test server from the live one and you're actually on the wrong server! ;)
