Inability to "Send-As" for users of Exchange 2007

by on Feb.01, 2009, under Windows Info

We’ve recently run into a situation that we realized is no longer possible when running Exchange Server 2007 on Windows Server 2008.

You cannot choose an alternate email address from which to “Send-As”, because the Exchange server will resolve your user object against the Active Directory, and replace whatever alternate address you’ve chosen with your user object’s default email address, as listed in the Active Directory.

Here’s the scenario-
Fabrimak is a company with many divisions. All of these divisions function as individual companies, and as such, have their own corporate identities, domain names, URLs, etc. However, due to the current trend of downsizing and leaner operational costs, they share a core Active Directory domain namespace, running Windows Small Business Server 2008 Premium Edition.

I know this is starting to sound like a test question for an MCSE exam, but bear with me.

The domain names in use currently are as follows:
Fabrimak.local (internal domain)
Tailswimtoys.com (default Internet domain in Exchange)
Consoto.com
Northbound.us

So, when users of Fabrimak’s internal network open up Outlook 2007, and create a new outgoing email, manually select to show the “From:” field, and choose to use their ‘user@consoto.com’ address, the mail recipient sees that the email came from ‘user@tailswimtoys.com’. This is because the outgoing email address used is decided when Outlook resolves the user account used to log into Exchange against the Active Directory, returning whatever address is listed as the user’s default. (Usually managed in the Exchange Console with the Recipient Update Policy.)

Even if you choose to show the “From:” field, and select an alternate (albeit valid) email address, the Exchange server will change the outgoing address used to your user account’s default outgoing email address.

Apparently, this ability to “Send-As” was purposefully removed by Microsoft, during the codebase rewrite of Exchange server.

However, (with the help of some friends from Redmond) there is a workaround. Allowing this “Send-As” behavior *is* possible. The workaround entails the use of Mail-Enabled Distribution Groups, and the removal of the Recipient Update Policy from the user account.

Details coming in my next post.

Running Windows 7 Ultimate in production – Day 3

by on Jan.28, 2009, under Windows Info

I can’t say enough how much of an amazing change this is from all previous versions of Windows. A ton of hard work went into this, and it shows. This release marks the very first time that all of my applications work together at the same time. I can now sync my phone using bluetooth, and access it’s internal storage directly from explorer.

There is an issue with the fingerprint reader being recognized after waking my Lenovo X61. I assume it’s because there isn’t a USB device bus scan immediately after wake-up. It doesn’t matter too much to me, though.. You can click on “Switch User”, and then the fingerprint reader will be recognized, and works for login.

Testing Exchange Connectivity

This is a *very* excellent site for testing things like Exchange Server SSL configuration, and ActiveSync problems… Chances are, your configuration is incorrect… ;)

Running Windows 7 Ultimate in production – Day 1

by on Jan.26, 2009, under General Info

I was able to run Windows 7 Ultimate all day. It was convenient, faster than Vista, and has as much eye candy as OS X or KDE. This morning, a few minutes before work started, I installed Windows Live messenger, Office 2007, and Connectwise. All applications worked correctly, except for Connectwise, which was fixed using compatibility mode.
3rd party apps installed and working correctly so far are:

Filezilla
Connectwise
Putty
Sun Virtualbox
Mozilla Firefox
IBM Fingerprint reader software
Western Digital MyBook software
AVG 8.0
T-Mobile Dash Smartphone software

Reactions to a phishing attempt…

by on Jan.07, 2009, under Amusement

I received this letter via email. (even making it through Message Labs’ mail filters…) Impressive that they can understand mail filtering well enough to get these messages through, but they can’t get a mail server admin job? Anyway, all links in this message point to one of my favorite scambaiting sites on the Internet, 419eater.com. Check it out, it’s hilarious! You guys rule!! Keep fighting the good fight!

Dear Friend, (you wish)

I am Dr.Khalid Hachana from Bahrain. (Sure you are.)

I have been diagnosed with Oesophageal cancer. It has defiled all forms of medical treatment, and right now I have only a few weeks or months to live. (That’s terrible!)

I am very rich, but was never generous; I have given most of my assets to my immediate family members. (As would I, or any of us)

However, I have decided to give alms to charity organizations. I cannot do this by myself anymore because of my ill health. (Bullshit. Even if I had terminal cancer, I could make a phone call to my lawyer much easier than spamming millions of unknown people on the Internet. You’re rich, you just said so. Whip out your iPhone and send your attorney some video email with your requests. Bahrain isn’t exactly lacking in infrastructure… Stop bugging me, I’m trying to *earn* _my_ living…)
I once asked members of my family to give some money to charity organizations, but they refused and kept the money for themselves. (Now, he’s asking for your alliance with him against his “evil” family… Probably the kind of guy that gives *tons* to charity… Sure. He’d vote you out on “Survivor” the first chance he got. And it would probably be a “blind-side”, too.)

I have a huge cash investment of $18.000.000.00(Eighteen Million dollars) with a finance house abroad. I will want you to help me collect this invested sum and dispatch it to charity organizations around the world. You will take out 10% of this fund for your assistance. If you think you can help me achieve my last wish before I die, please reply only through my private email addresses; drkhaliddrkhal@aol.com or drkhalidhachana@live.co.za (the hook. 18 million dollar$!!! I can haz moneys??)
You can send me your full names, address, telephone and fax numbers, date of birth and occupation. Once I receive your complete personal details, I will forward them to my attorney, barrister Romain Coleman. (Couldn’t you have just phoned/emailed him your request to liquidate your accounts to charitable organizations? I’m pretty sure that I could do that…)
I will present you to him as my next of kin and he will contact you to give you detailed instructions of what you have to do to receive the funds on my behalf. (Ummm…. Isn’t identity theft a crime?? I’m not going to commit a crime to help you, dude.. I don’t even know you..)

I will be waiting for your immediate response. (hold your breath whilst you wait, will you?)
Regards and bye!

Dr.Khalid Hachana.
HELP ACCOMPLISH MY LAST WISH. (Was your last wish to be driving a Hummer around in the slums where you probably live? If that’s the case, then I say no. Good day, sir… And good luck with the dying from cancer thing…)

Microsoft implementing subscription-based services

by on Dec.27, 2008, under Windows Info

You know, some of you out there in the ether may get the idea that I don’t like Microsoft. If you get that feeling, I can understand why. But, you’re wrong. I have a great respect for them, and their software. It has often been known to be insecure, incomplete, ineffective, and annoying. That being said, consider the start. A group of slacker nerds dropped out of college, lived, slept, ate, and breathed code just because they wanted to, and sold their {not entirely finished/owned/understood} OS to a rather large computer manufacturer with *NO FRIGGING* possibility of knowing if they could pull it off. But, they did. And they succeeded. And their OS and software runs on millions more machines than the OS you and I wrote. For that, I really admire Microsoft. They just did it. Did you?

So, this news of subscription-based access to their OS and software is extremely interesting to me. All I’ll say about it is that my admiration for Microsoft would grow logarithmically should they decide to implement a program rewarding an exemplary GPA for students paying their subscription fees. A straight-up 4.0 GPA student should enjoy all of their services for free.
Maybe they should receive an all-expenses paid trip through UC Berkeley for their CS degree. Microsoft possesses the ability to make an important difference here. I believe that educating our children better benefits not only us, but the entire world.
