That's right, you can't beat the scale of gmail. But you can run a filter yourself, and because your personal filter will be more adapted to the specific spam you get, the results can be suprisingly good. https://spamassassin.apache.org/ https://spamassassin.apache.org/ is one of the old ways of doing that, it should work fine for your scenario. > Also, isn't there a hosted service, SaaS or something, that offers filters and allow for feedback (users marking messages as spam), like a pay-as-you-go trained Bayes filter? Yes, tailored for blog-comments even. It is called akismet and run by Automattic, the company behind Wordpress, see https://akismet.com/ https://akismet.com/. It is very effective and a good solution without costs if you are willing to give the comment data to an US-entity, which is very critical in Europe where I live. Though you can't train it yourself from outside of Wordpress, to my knowledge. For mails there are several spam filter services, like http://www.mailroute.net/ http://www.mailroute.net/, but I do not have any experience with them.
