In the FOSDEM deliverability meetups multiple spam testing tools were shared; the first of which looks extremely useful. Here’s the list I can remember:
- Abuse.io - [inbound+outbound] all round Open Source abuse detection toolbox, including for spam
- CanIt - looks like it was bought by another firm and has not received much love since
- Spam experts - [inbound+outbound] proprietary tools used by big ISPs for filtering
What’s missing?
