Build numbers and release dates for Exchange Server

I've spent a little bit of time this week trying to guess a Exchange Version and SP (I know that SM tell you that! ) but looking for it in a Dump file without access to SM it's harder, so I've remember a very useful KB article, that I used in the past and by coincidence a colleague of mine has recently send it to me, so here it is the table and Kb link hope that this will help you all in the future (thanks Tude!);EN-US;158530
