Exchange: How to Configure Bulk Message Restrictions on DL's Using Admodify

Summary:

Restricting who has access to send to distribution lists or a particular user is a neat feature. For example, this comes in handy where you need to restrict who can send to a large distribution list or who can send to say a VP. However there is no native tools if you wish to configure restrictions on multiple Distribution lists or users at once. This can be accomplished by using ADMODIFY.

1. Download ADMODIFY

ftp://ftp.microsoft.com/PSS/Tools/Exchange%20Support%20Tools/ADModify/


2. Run Admodify and select all your DL's that you wish to perform restrictions on.

3. Once you have selected your DL's go to the custom tab. Select "Make a
Customized Attribute Modification" Attribute Name = Authorig,
Value= DN of user (Example:
CN=last\, first(Consultant),OU=Contractors,OU=Contractors,DC=HQ,
DC=Company,DC=net)

4. Open your DL's in ADUC and verify that the restrictions have been set.

The attribute for "From Authenticated Users Only" is msExchRequireAuthtoSendTo. If you would like to use this, enter this attribute in step 3 instead of Authorig.

I've a DL with restrictions, but still someone was able to mail to this DL from inside the company.
After checking the restrictions again, we didn't found anything wrong, all the other users (and also the one that could send the mail can't send to this DL). The person itself didn't tell us how he did it, but he can't do it the "normal" way.

Hi Chong,

I want to set the attribute "msExchRequireAuthtoSendTo" for more than 1000 distribution lists spread over multiple OU's. I don't want to set any other user restriction. I just want to ensure that the option "Authenticated USers only" is selected for all distribution lists. In this scenario, what do I need to enter for Value in step 3?

Thanks
Karsudha

If you are those who tend to under probate and you do not need extra help, then you can probably get by with Hogan . For men who are average weight, with no promotion of the problems that need a bit of Hogan scarpe donna with good support, durability and cushion, they should probably be a Hogan scarpe uomo . The motion control category contains the most durable, rigid and controlled sports shoes. Hogan uomo are specifically designed to limit the disease known as over probation.
