Spam blocker in Outlook 2010 is not working.

Question

I go into the program and add to the list of domains I want to block. It just does not work.
I am blocking them by going into Junk via opposite mouse button and then options and the Block Senders tab and then I click on add.
I add a domain as @donotwant.com  click apply and then OK.   I see it in the list even after I close Outlook and go back in.
Yet the emails are still ending up in my junk folder from that sender!!!  I have seen this problem mentioned by others on the web.
If this is a bug in 2010 then it should be fixed!!  if I am doing something incorrectly, please inform me.   Is  there a possible space being added to the end of the string by Microsoft that I can not see but is causing the problem?  
(I can not believe that the programmer who wrote this stuff would not use a trim string command to avoid the issue)
(My gosh from a programming standpoint this should be easy for Outlook.  Compare the list of blocked addresses to the incoming new emails and block the ones that match it on the list.  I think a Junior High School programmer can handle it.  
The kid would certainly Use an INString command to pull the domains that are blocked.) 
Not blocking these is really annoying.  I would appreciate any help offered.
Thank you

Hi,
This is the default behavior for emails sent from blocked senders in case some users want to check the email in the Junk Email folder.
If you want to permanently delete emails from a domain senders, we can set an Outlook rule to do this. Please follow the steps below:
1. Click on Home tab > Rules >
Manage Rules & Alert
2. Click New Rule…
3. Select “Apply rule on message I send”, click Next button.
4. Tick the check box before “with specific words in the sender’s address” in the
Select condition(s) box. Click
specific words and type @domain.com (you need type @donotwant.com) in the box and click
Add button. Click OK.
5. Click Next.
6. Select the action “permanently delete it”. Click Next. Click Next.
7. Make sure the option “Turn on this rule” is selected. Click Finish.
Now, all emails from @domain.com will be permanently deleted.
In addition, we can consider to set block list on the server side to prevent the emails sending to your mailbox.
