That includes all of my legitimate customers... If you want I can get you some legitimate subject lines :-). A few points: - There is a difference between 'real' companies that do stupid/illegal things and 'criminal groups' (who run their operation outside of the law, therefore all their email is spam). How do you detect the difference? - For 'real' companies: How do you 'prove' a relationship between the sender and recipient for a certain part of content? Example: There might be a legitimate relationship between a company and a customer. Company has a crazy idea and wants to start emailing its normal newsletter to everyone, with or without optin. It has now sent, the same email, to two groups. For the first group it is spam, for the second it is ham. - I have seen a lot of normal emails being abused by phishing. They basically copy 'everything' and put one bad link in it. The only difference is that they 'sell a little harder' (get a free iPad) or 'create a little bit more fear' (you internet will be shut down) than in normal emails that we send. The line that you are trying to detect is very thin. But this refers to point #1, basically. Regarding point #1: I think that Google and MS are doing a good job in 'wanting' authentication from 'real' companies. I wish they would publish an official statement saying that non-authenticated emails get spamfiltered for X-points at date X1 and Y-points a few months later, etc etc. Met vriendelijke groet, David Hofstee Deliverability Management MailPlus B.V.
