Hi Cory Well there is no magic answer to this problem, the connections you are seeing are more than likely NDR's trying to go back to the spammer that is trying to send spam into your company, check the BadMail directory on your Exchange server and you might see a lot of mail in there that cannot be delivered to someone in your org and it cannot be returned to the sender because they used a fake email address. The best way to combat this problem is to implement an anti-spam solution like MailEssentials from www.gfi.com, you might also consider upgrading to Exchange 2003 as this has a number of features to help combat spam. Hope this helps Mark Fugatt MCT, MCSE, Microsoft Exchange MVP Pentech Office Solutions Inc Tel: 585 586 3890 Cell: 585 576 4750 Fax: 585 249 0316 www.4mcts.com www.exchangetrainer.com -----Original Message----- From: Cory D. [mailto:coryd@xxxxxxxxx] Sent: Monday, August 04, 2003 1:05 PM To: [ExchangeList] http://www.MSExchange.org/ What is a good way to secure this connection? I have tested to see if I am an open relay and everything comes back fine. But I notice a lot of connections in my queue, what I want is for this to be as minimal as possible. I guess the first thing I could do is start to block a lot of the domains but that seems to be a little extreme. Any help would be great. Cory D.
