Joel, can you please provide information on the experimental method for specifying which IP addresses may be used to send mail from a particular domain?
The method of using DNS to specify that only certain IP address ranges may send mail purporting to be From: your domain has the potential to offer significant benefits for spam blocking as well as allowing us to reduce our reliance on other methods (eg the contentious services such as dynablock.easynet.nl which get debated on these lists). I would be happy to configure my servers to avoid checking the dial-up lists if such a method could be used instead, and I think that this would make a lot of people happy. The method in question has never taken off because of lack of application support. If we make all mail servers in Debian support it then that could be what is needed to make it a success. I would be happy to devote some coding time to this if it can result in a net reduction of SPAM. -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
