Well OptusNet's cable ranges are in the DUL despite OptusNet filtering outbound 25 by default. You can get port 25 outbound opened on request but it doesn't do you any good when you are listed in the DUL. It doesn't matter if the address belongs to a business or a residential user. Everyone has the right to send email directly. As far as I can see the only reason for DUL existing is that ISP's are too slow at reacting to abuse reports and / or fail to send messages to say what action they took. People got feed up with [EMAIL PROTECTED] being a blackhole from which they if they were lucky got an automatic acknowledgement of the messages. In the end people reacted the way you would expect them to react when that perceive that they are being ignored. They stopped reporting and turned to other means (DUL, SpamAssassin, etc.). Mark
