New RBL added -- SORBS DUHL By Peter M. Abraham June 2004 Dynamic Net, Inc. has added SORBS DUHL as a real time black hole list on Sunday, June 27, 2004 to help protect our customers against the growing amount of spam. SORBS DUHL:  The DUHL (Dynamic User Host List) is a third party database maintained by http://www.sorbs.net/. This database contains IP addresses that have been confirmed as being assigned to Internet Access users in a dynamic fashion, meaning the IP addresses are not static assignments.  This is typically the method of IP assignments for dial-up, DSL, ADSL, and Cable Internet Access clients. Such IP addresses are a major source of spam today because spammers have found ways to take over PC's using these connections. Various Trojans and other recent virus outbreaks have been written to exploit PC users' security weaknesses and use these IP addresses for spam, in most cases without the knowledge of the end user or the ISP. Dynamic Net, Inc. does not condone running any type of SMTP engine or mail server on dynamically assigned IP addresses and in many cases, doing so is a violation of the ISP's Terms of Service. Dynamic Net firmly believes that ISPs' authorized SMTP relays should be used at all times.  If any IP address listed in the DUHL attempts a connection to the Dynamic Net mail servers, that connection attempt will be rejected. Please feel free to call us toll free at 1-888-887-6727 or internationally at 1-717-484-1062 if you have questions. Thank you. P.S.  It is important to remember that we have a special email server set up that uses zero RBL's.  If you believe you would be better served by our company to have your account use that special mail server, please let us know.  There is no cost to switch; it is just a matter of scheduling and coordination.
