Exchange 2003 SP2 technology preview

Microsoft is making a “community technology preview” (CTP) of Exchange Server 2003 service pack 2. This is pretty cool. Get it from this link (which should be live shortly). I’m particularly interested to see how people put the Sender ID tools to use.
Update: the Exchange team blog has a list of FAQs about the CTP. Note well that the CTP build isn’t supported by PSS and shouldn’t be run on production servers.
