Exchange 2007 Spam filter Whitelisting

by | Apr 7, 2009 | ,


We’ve recently upgraded our Exchange 2003 server to Exchange 2007.  There’s a lot of new and updated features in this version.  The Anti-Spam features seem to be working very good but are catching some legitimate emails.  I found the following shell commands for adding email addresses or whole domains to the white lists to keep them from getting blocked. 
If you are like I was and didn’t have a clue what shell commands meant, open the Exchange Management Shell from the start menu.  It’s a command prompt for doing various command line based tasks.  You can perform pretty much everything you can normally do from the gui interface from a command line.  This makes creating scripts to perform repetative tasks a snap.

  • Whitelist a domain:
       Set-ContentFilterConfig -BypassedSenderDomains somedomain.com,someotherdomain.com
  • Whitelist an address:
       Set-ContentFilterConfig -BypassedSenders     foo@somedomain.com,foo2@somedomain.com
  • Copy the config of the content filter to the clipboard for viewing in a text editor:
        get-contentfilterconfig | clip 

    • I found these commands here.

    You will only be able to play un-encrypted DVDs with the above installs.  You have to get libdvdcss which has legal issues in the US.

    Missouri Capital building in Jefferson City

    We took our kids to visit Jefferson City, the capital of Missouri. During our visit we saw the capital building, Governor’s mansion and a few other historic sites. It was a very interesting visit. While we were there the House of Representatives was in session and we were able to watch some of the proceedings. Our democratic process is quite a complex thing.

    Remote desktop connection in Linux

    by | Mar 8, 2009 | ,

    I installed a fresh copy of Fedora 10 (which I’m thinking is my favorite Linux distro so far) on my laptop and have been seeing what all I can and can’t do that I normally do on a regular basis.  Right away I wanted to use Remote Desktop to connect to my Windows Server 2008 box.  Well, I coulnd’t find a Remote Desktop client.  I jumped on Google and found mention of RDesktop.  I managed to get that installed and it worked, but I had to launch a terminal prompt and type rdesktop [ServerName].

    I poked around some more and found mention of TSClient.  I had gone to the Add/Remove Software tool and searched for remote desktop and rdp and a number of other things, but hadn’t thought to search for TSClient.  It makes sense now that I think about it since remote desktop is also called Terminal Services.

    Anyways, to get a GUI based Remote Desktop client search for TSClient and install that.  As a bonus it also installs a VNC viewer as well, which is another tool I use.

    Show all files in Mac OS X

    by | Mar 5, 2009 | ,

    In my quest to learn more operating systems and just show more of my geekiness I’ve been playing with installing OS X on a regular PC and on my laptop.  Clearly they made OS X to work with a small subset of hardware and had no intention on letting anyone experience the Mac OS outside of their hardware.

    One of the first annoyances was that Apple hides all system files and doesn’t have an easy way to turn them back on.  Here is a command to make all files visible in the Finder application:

    (From the terminal)
    defaults write com.apple.finder AppleShowAllFiles TRUE

    (This next command kills all instances of Finder to make the change effective)
    killall Finder

    Re-open Finder and you’ll be able to see all system files now.

    Linux commands – mounting Windows shares and configuring sound

    by | Mar 1, 2009 | ,

    Command to mount a Windows share to a folder in Linux:

    mount -t cifs //[ServerName]/[SharedFolder] /[MountFolder] -o username=[ServerName]/[Username],password=[Password]

    For the mount folder I created a folder under /home/[MyUsername] using MKDir /home/[MyUsername]/Videos

    Remove the brackets from Servername etc.  Also make sure there’s no spaces between the = and the username or password.

    Dancer

    Sometimes moments happen and you just don’t have time to get your camera out in time. Or when you do get it out the lens you have on doesn’t give you enough of the scene. And then the moment is gone. I still like how this turned out, but I wish I had time to get it a bit better. She started spinning and dancing while we were eating at Olive Garden and I thought oh, that would make a good shot. By the time I was prepared she decided she’d done enough. She did decide to dance with our waiter as you’ll see tomorrow.
