IP Address 62.149.95.74 was found in the CBL. It was detected at 2005-10-08 06:00 GMT (+/- 30 minutes). It has been relisted following a previous removal at 2005-10-06 07:46 GMT Looks as if it was removed and then re-added - that means that you are an open relay (or not secure!) Get it sorted before you try and connect your server to the internet again! ...Spence ________________________________ From: Mohammed Naimathullah Siddiqui [mailto:mailnaimathullah@xxxxxxxxx] Sent: 09 October 2005 08:48 To: [ExchangeList] Subject: [exchangelist] Delivery Status Notification http://www.MSExchange.org/ Hi, We exchange 2003 server on windows 2003, when ever sending e-mails outside we are receiving these replies.
