I have never done this but have heard of it. Can't you just add an entry in the HOSTS file for yahoo.com and point it at an IP address such as 10.10.10.10?

We are just trying to block mails that are addressed to yahoo.com fro our exchange server. I hope sender filtering is to filter mails which are addressed to our exchange server from any other external domain (eg: incoming mails from yahoo.com is blocked using sender filtering) Thanks, Mahadevan. _____ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of shorabh upadhyay Sent: Monday, May 22, 2006 2:57 PM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Recipient filtering - Exchange 2003 Hi, I thinks you are looking for " Seder Filtering " not for recipient filtering.Becasue you are looking to Prohibited to send the mails to a particular domain in your case which is @ yahoo.com. You have to add this Domain in Sender filtering instead of recipient filtering.

Currently our exchange is configured to forward all mails to one of the smart host (remote machine). We have configured sender filtering and it is working fine. But if we configure the recipient filtering to block outgoing mails to a particular domain (Say for eg: @* yahoo.com*), it is not working and still we are able to send message to that domain. Kindly let me know if the recipient filtering will work in our current exchange configuration (forwarding mails to smart host).
