I had this problem before, what you have to do is just check your logs to get the ip address of that computer who is sending you these emails and best way is to block the ip on the firewall level. Else you can go inside the exchange enterprise and you can put the decline filter on that Ip address Basit -----Original Message----- From: Eric Lanyon [mailto:ELanyon@xxxxxxx] Sent: Fri 3/5/2004 11:37 AM To: [ExchangeList] Cc: Subject: [exchangelist] NDRs and Bad Mail http://www.MSExchange.org/ I am running Windows 2000 Server with Exchange 2000. My clients are running Outlook XP with a few 2003 clients. We were getting TONS of NDRs which were filling up the queues and bogging down the server. The NDRs were replies to SPAM messages to non-existant users, etc. It was decided to turn the NDRs off to help reduce the number of queues and the load on the Exchange server. We are still getting tons of emails to the Bad Mail folder...which keeps filling up. Is there a setting that we can enable that will prevent emails from going to the Bad Mail folder? I know we could script something that will autodelete everything in the folder, but itâs nice to manually do it so we know whatâs going on with it. Any suggestions on this?
