The link to the CTP release of Exchange 2003 sp2 is active now. Just an
FYI that this is not production ready and should only be used in a test environment.

Microsoft will be releasing a CTP preview of Exchange 2003 sp2 on Friday according
to many different sources. This service pack has some great updates in it with regard
to mobile messaging and spam filtering. Since this is not released software, only install
on non-productions sytems and be sure to test thoroughly.

Not mail related but.... there is a great article on securityfocus about Microsoft's
'honeymonkey' project. It great to see them being pro-active about finding security
vulnerabilities.... hopefully that translates in to much more secure client OS in Windows
Vista.

Enterprise Magazine posted a story this morning about Microsoft including their
speech server technology in a future release of Exchange, most likely as part of
their unified messaging strategy. Should be interesting to see.
