Here is a pretty ugly bug with Exchange 2003/sp1 and the entourage client
that you need to be aware of if your running this environment.

Thanks to Steve Antonio (MS Exchange EE group) for pointing out two great
papers on exchange permissions. This seems to be one of the most difficult topics
for exchange administrators and it's good to see some deeper level docs covering
this area.

There are two permissions papers now.

In case you aren't already, you should head over to this site for assistance with
setting up an SPF record for Sender-ID lookups. The more of these we get published
the better as AOL is already using them and MS will start checking inbound mail for
hotmail and msn next month.
http://www.anti-spamtools.org/SenderIDEmailPolicyTool/Default.aspx
Looks like MS may be coming around on the patent issue with Sender-ID and
making it more palatable to the open source crowd. Good to see progress is being
made here.

PalmOne just released a new treo, dubbed the 650 that now has support
for Exchange 2003 active sync. Looks to be a nice upgrade although I still
think the keyboard on the BB devices is much better.

It looks like we may not see a release of exchange next year from MS, especially
since they are already back pedaling from their previous announcement of Edge services.
This is really a sorely needed niche of Microsoft's and I hope there is more going on
with this than meets the eye.

Here's some more comments from eWeek on the Sender-ID/IETF issue:
http://www.eweek.com/article2/0,1759,1644655,00.asp


According to the guys over at moongroup.com, the Sender-ID spec has been shot down
by the IETF due to patent issues and will not become a part of the standard (barring any
last minute changes by MS). Hopefully things will change but right now it doesn't look
good.

    According to slashdot.org, MS is negotiating with OSI on a possible open
    source license for SenderID. The information is based on an interview with newsforge's Larry Rosen. Hopefully this will bring resolution to this one sticking point with SenderID and the open
    source community.

    Not mail related but MS just released a nifty little tool that will give

    even goes in to showing what processes are utilizing that port (XP and W2k3

    Looks like support for the SenderID spec is wavering from some of the
    open source pundits. I can see both sides of this story but we really
    need to push that stuff aside and get this roled out asap.

    Tumbleweed just released version 6.0 of MMS (now called EMF) that supports

    running on their proliant servers. It's not that surprising to see HP
    make this move since they have been doing alot more 'open source' type
    stuff but it will be interesting to see if internally things change
    as far as their mail platform. Should they decide to run Sendmail instead
    of Exchange, that would be a huge blow to Microsoft (condidering HP is
    one of the largest supporters of Exchange - including providing a large
    portion of the technical support for Microsoft).

    Microsoft also released updated tools in their all-in-one

    has been a highly requested feature. Previoulsy, most people (like me)
    just used a batch file ran by AT to delete the contents of this folder.
  • Exchange 2003 Tools
  • Microsoft just released sp1 for Exchange 2003 and the Intelligent

  • Exchange 2003 sp1


  • Exchange 2003 IMF


  • Just a word of caution here.... sp1 cannot be removed once it's installed. Please make a full backup before and after installation. I think this is a poor decision on Microsoft's part to not include a remove option. Hopefully it will not be needed. ;-)

    Looks like Microsoft may be working with the SPF group to merge
    both SPF and Caller-ID specs. This would be a huge boon for the
    industry and shows that the 'new' Microsoft is alive and well. Here's
    a thread outlining the first steps:
  • Caller-ID and SPF Merge

  • Thursday, May 20, 2004

    There is now a project under way at SourceForge for the creation of
    an event sink for exchange to do SPF lookups (Sender Permitted From). This
    is similar to Microsoft's 'Caller-ID' fuctionality and is currently being
    tested by AOL and others.
  • SPF Event Sink for Exchange
  • According to a survey done by Commtouch, 71% of all spam servers are
    located in China. Apparently cheap labor is not the only thing plentiful
    over there. Major ISP's need to step in here and start filtering some
    of this stuff as the trend is getting worse every month.
  • 71% of all spam server in China
  • Microsoft today announced they are submitting their Caller-ID technology to the
    IETF for consideration as in industry standard. I really hope this thing gets legs and gets accepted quickly and then adopted quickly by the major ISP's. We are all drowing in spam and this could take a big chunk out of the equation.
  • Caller-ID
  • Symantec announced yesterday they are buying Anti-spam vendor Brightmail
    for a boatload of cash. IMO, Brightmail has the best anti-spam software
    in the market so this is a real score for Symantec.

    Sybari just released an updated build of Antigen (7.5, SR3, Build 1314)
    that has support for Exchange 2003 sp1 using ESE mode. Hopefully we will see sp1 released at Tech-ed in two weeks.
    Novell announced today that they will offer the evolution exchange connector for free starting May 14th. This allows a linux desktop running evolution to connect to an Exchange 2000 or 2003 server with a limited subset of the fuctionality of Outlook. I still think Outlook is a much better client for exchange but if your forced to use a linux desktop at least now you can use evolution (with the connector) at no additional cost. Previously each desktop using the connector had to have an exchange connector license from Ximian (in addition to a CAL for Exchange).

    I'm not really sure how Novell is going to make money from this but I'm sure they have lots of really smart people thinking about that. Maybe Microsoft should thank Novell for helping sell Exchange CAL's.
  • Novell Evolution Connector for Exchange
  • Here's a good list of the top 10 problems with databases not
    mounting in exchange and their solutions. Hopefully you will never

  • According to multiple sources inside Microsoft, they plan to release
    the Exchange 2003 IMF (Inteligent Messaging Filter) for free via a web
    download very soon. Previously it was announced that this would only
    be available to those Microsoft customers who were part of their Software
    Assurance program. It's good to see Microsoft took feedback from their
    customers and decided to provide this to everyone at no cost. I'll post
    a link to the download when it's available.
    I've been testing the new Gmail service from Google and so far

    I was just alerted that exploit code has been released that uses vulnerabilities found in MS04-011:

    Microsoft is aware of code available on the Internet that seeks
    to exploit vulnerabilities addressed as part of our April 13th security updates. We are investigating the situation to help protect our customers. Specifically, the reports detail exploit code that attempts to use the IIS PCT/SSL vulnerability on servers running Internet Information Services with the Secure Socket Layer authentication enabled. This vulnerability is addressed by bulletin MS04-011. Customers who have deployed MS04-011 are not at risk from this exploit code.

    Microsoft considers these reports credible and serious and continues to urge all customers to immediately install the MS4-011 update as well as the other critical updates provided on April 13th. Customers who are still evaluating and testing MS04-011 should immediately implement the workaround steps detailed for the PCT/SSL vulnerability detailed in the MS04-011. In addition, Microsoft has published a knowledge base article KB187498 at
    http://support.microsoft.com/default.aspx?scid=kb;en-us;187498 which provides additional details on SSL and how to disable PCT without applying MS04-011.

    We expect to see additional exploits and proof-of-concept code targeting the April 2004 security bulletin release in coming days and weeks, potentially including worm or virus examples.

    many exciting things coming up in the next few years. It will be interesting to see
    if they are able to 'fix' the spam problem since Bill Gates stated it would be resolved
    in two years. The products/solutions they have to address this issue are well thought
    out but will take the adoption of all the major ISP's to be successful.
