I have a static IP address and run a smtp server. My isp puts all the static ip addresses into the dns blackhole lists. I use my ISP's mail server as a smart host and send mail through it. If a user such as myself misconfigures their smtp server to act as an open relay then (hopefully) a receiving mail server will check the dns blackhole lists and refuse to accept the email. Thus users misconfiguring their own email servers should no longer be used as a source of spam. > > ALSO, most ISPs that offer a businss service remove this restriction. > > THAT is indeed a good point, first remove functionality and then make > customers pay extra. Unfortunately this seems a common business tactic, but perhaps it is thought that business customers are less likely to misconfigure smtp servers? Regards Chris
