Spam is a nuisance and there is a legitimate need to stop it. Implementing RDNS is not the answer, at least not yet. I say not yet, because it requires *ALL* ISP's, globally, to allow their customers to register their(isp customer) mail servers IP address into RDNS, regardless if you are a home dsl/cable user or a business, for it to work.
Actually, this is incorrect. It only requires that all ISP's provide their customers with an SMTP server that has proper rDNS configured. You can still run an SMTP server from whatever location: home/office - cable/DSL. You only need to use your ISP's properly configured-for-rDNS SMTP server as a mail gateway. This is why I say there are options at your disposal for getting around your lack of rDNS control. You do have options, it's not a false-dilemma. OK, I really am finished with this thread now. -- Derek Schaible <dschaible () cssiinc com> CSSI, Inc.
