X-BeenThere: freebsd-isp@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Internet Services Providers List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 21 Feb 2005 03:26:39 -0000 sendmail[93922]: j1L2kZa5093920: SYSERR(root): mx1.distinguish.com. config error: mail loops back to me (MX problem?) I know everyone has seen this message at least once in their life from improperly configured sendmail. However, my log is filling up with these messages for domains I do not host.... and when I dig the mentioned host, it always resolves to localhost (127.0.0.1). This happens over and over again on for domain after domain. Are there really that many unskilled admins who publish their mail server's address as localhost, or is this some sort of hack that I should worry about?
