Hi All,

Can I blacklist a certain "from" address in Exchange? I have a lot of spam from a few addresses. I do not want a special spamfilter, but just to block 2 or 3 addresses.

If this is SBS 2008/Exchange 2007 you can do so by going to: Exchange management console | Organization configuration | Hub Transport | Sender filtering - properties | Blocked senders | add

Hi Rob,

Did not notice it was you, but yet again, your solution is the one! THANKX

Additionally this information:

To enable recipient filtering:

Start Exchange System Manager.
Expand "Global Settings"
Right click on "Message Delivery" and select "Properties".
On the "Recipient Filtering" tab, check "Filter recipients who are not in the Directory" and click [OK].
You should then be presented with a message box stating:

"Connection, Recipient, Sender ID, and Sender Filtering must manually be enabled on specific SMTP virtual server IP address assignments as they are not enabled by default ..."

The second part of the configuration is to enable recipient filtering for the SMPT connection:

Still using Exchange System Manager, expand the server list, under the server expand the list of protocols, under SMTP right click "Default SMTP Virtual Server" (or the name of the SMTP server to configure) and select Properties.
On the "General" tab, click [Advanced...].
For each IP address listed (normally there is only one), click [Edit].
Check "Apply Recipient Filter"
Then [OK] to close.
All incoming emails are now checked as soon as they are received.
