Messages from specific senders can be blocked by implementing sender filtering. Blocked senders are specified in Global Settings Message Delivery properties Sender Filtering tab (see screenshot).
The Senders list is saved in the msExchTurfListNames attribute of the Default Message Filter object. It is a multi-valued attribute. It can be exported using ldifde/csvde if you take the trouble to find out distinguishedName or objectClass of the attribute.
Here’s a little script (… quite complicated actually, considering it can be done using either of the above methods using a single command… ) that will export the list to a text file –
getSenderFilterList.vbs (zipped).
Usage:
getSenderFilterList.vbs /f:filename.txt – exports to file
getSenderFilterList.vbs /f:filename.txt /s:y – exports to file and suppresses console output
