Re: Blocking Top Level Domains

Hi Medthump,

Thanks for posing in our newsgroup and also for Alexander's great input.

I am sorry for the delay response due to the weekend.

If you would like to block some mail from some top level domains, please
refer to the following steps:

1. Open Exchange System Manager.
2. Right-click Message Delivery under Global Settings, and click
Properties.
3. Switch to the Sender Filtering tab, click Add to add the domain you want
to block:

*@*.ca
*@*.tz

4. Click OK.

Then, please apply the Send Filter to the SMTP virtual server which is
responsible for receiving e-mails.

1. Go to Domain(Exchange)\Administrative
Groups\Servers\Servername\Protocols\SMTP.
2. Right click Default SMTP Virtual Server and select Properties.
3. On the General tab, click Advanced.
4. Click Edit and select Apply Sender Filter.
5. Click OK two times.

Hope this helps. If anything is unclear, please feel free to let me know.
I am standing by for your update.

Best regards,

Robert Li(MSFT)
