For E2k, I donot remember right now, how to block unwanted inward e-mail. However for blocking outbound e-mail to unwanted domains, you can create an SMTP connector, add all the unwanted domain names as "domain.com" and point the same to bogus IP address. Alternatively, you can point the SMTP connector to a valid SMTP host like Win2k PRo SMTP. Configure teh Win2kPro so that it just receives e-mail and does not send it. You can later view or delete the mail files from the Inetpub\mailroot\out folder of teh Win2k Pro machine. Note that the above is NOT a cool solution. When I get or remember any way to block unwanted inbound e-mail, I will post it here. Regards Sakhawat Hussain
