Any DNSBL that blocks Google's mail servers, other than perhaps in sufficiently serious situations to justify this level of collatarel damage, shouldn't be recommended. You should provide a way for customers to opt out of your blacklists. Many people are perfectly happy to run their own spam filtering software and retain the capability to skim (or analyze) their spam. If you provide a way for your customer to do this, point them to it. If not, that is a failing on your part. (Though of course it's always possible you have cost/benefit arguments that justify not providing that service.) Some people would really like email to be as reliable as possible, even if that means they have to wade through a lot of spam. At least this gives them ability to whitelist sources that are important to them personally. David Schwartz <[email protected]>
