Here's a new whitepaper released by MS on using recovery storage groups in Exchange 2003. Recovery storage groups alleviates the need to have a 'recovery server' to restore individual mailboxes (a common occurence in my office).

An article posted at 'the register' quotes messagelabs as stating two thirds of all the spam were seeing is coming from computers infected by viruses such as Sobig-F. This theory was brought up when the virus first hit because of the built-in timeout the virus contained. Seems like the spammers may be working with Dr. Evil now.

Heads up for a now OWA vulnerability on Exchange 2003. This one seems kind of esoteric but it's better to be safe than sorry.

A number of news sites have been reporting a flaw in exchange that allows users to send spam if the 'guest' account is enabled on the server. I haven't seen an official repsonse from MS on this yet but it's a good idea to check your servers just to make sure that account is not enabled.

Looks like Microsoft is getting serious with spam identification. This looks to be
a great addition to exchange.

MS released today the rights management add-on for Windows 2003. This will allow corporations to lock down content (ie, emails with attachments) to specific individuals/corporations. You can restrict a message from being printed, forwarded, etc. I tested this in beta and it had a few bugs so hopefully those were ironed out before the release.

KC Lernson from the exchange group posted a link to some papers MS has done on how MS runs MS. Good stuff.

Looks like MS may be re-thinking the timeframe for adding a sql backend to exchange. I would imagine it all depends on how quickly the yukon stuff comes together and the overall quality. Fun Stuff.

Here's a review of the top anti-spam packages for enterprises. Brightmail comes out on top and it is a package we use with great success. If you require ultra-low false positives, this is the only package to go with.

My posting will be limited this week since I will be at the PDC but if I get a chance, I'll post.

As for the PDC, longhorn is taking shape nicely, I hope they get it right on the security front in addition to the new eye candy.

Over at www.e2ksecurity.com they point out a new application from Omniva that helps making secure email in exchange easier. Since this sits on the server it should be easier to roll out than client based solutions.

Here's the fix if you happen to have a problem with OWA after
applying the 5.5 hotfix below. Apparently some customers are
not able to view messages in OWA until they hit reply or forward.

Heads up on a hotfix (posted originally by David Lemson) for
exchange 5.5 with outook 2003 users.

David Lemson from the MS Exchange group provides a great tip on configuring Exchange 2003 to reject invalid addresses during the SMTP converstation. I wished they would have had this feature when I was taking care of a bunch of 5.5 servers. I got tired of looking at all those NDR's in my IMS queues with <> senders.

Robert has a good thread going about the new development process they are attempting with longhorn. The comments are fast and furious, hopefully this initiative gets off the ground and has the effect on developemnt they describe.

For anyone who hasn't heard, AT&T now has the first MS smartphone introduced in the US market. It's still running smartphone 2002 instead of 2003 but is still pretty cool. I think I'll wait until someone comes out with a smartphone 2003 device that has an integrated keyboard. I do way too much email to not have easy input.

If you start to see email bounce from AT&T, this is why. Not sure how
well this is going to go over with their users after they start missing alot of important email.

This is a great add-on that I recommend to alot of power users
to make it easier to modify level 1 attachments in outlook. Much
easier than editing the registry and priced right.

Is this the future of telecom as we know it? I know this has to completely freak out the telcos. I'm all for paying them a few less dollars.

Internet Telephony Shoot-Out: Skype vs. SIPphone!
I constantly get asked by users why we can't stop somebody from sending an email with a spoofed address. This idea (SPF) sounds like it would go a long way to fixing this with the side benefit of stopping a boatload of spam. I wonder if the exchange group is looking at this?

SMTP SPF: Senders Permitted From
Off the topic for exchange but the ideas layed out here by Mr. Greene are right on IMO. Hopefully people at MS are listening since now is the time to get this stuff in. I think now is also a good time to sacrifice a good bit of compatiblity to move forward with better/more secure interfaces and methodology. Forget about trying to fix all that legacy code and get this stuff right the first time.

Dylan Greene dot com - How Microsoft could stop spyware and adware with Longhorn...
Evan Dodds from the exchange group pointed me to this article about microsoft's latest internal rollout of exchange 2003 (now a few months old but still very interesting.) This article will give you alot of insight in to building a large/scaleable installation of exchange and what tradeoffs were made to maintain published recovery times.

Good reading!

Here's a critical patch that has not received much press. If your running
Sybari's Antigen on an Exchange 2000 server, apply this patch immediately
(this patch is also included in the latest exchange rollup). The story here
is a bug in Microsoft's handling of event sinks causes corruption in the .stm
file. Sybari is aware of it and recommends installing it as well.

This one cost me a days work restoring a db. Fun stuff.
