I’ve added it to the “tools” section yesterday. It’s really a useful tool.
iSECPartners publish frequently on SSL vulernabilities. There is a great paper describing common attacks against SSL/TLS that I referenced a lot in this paper and e-mails all over mailing lists, it is just well done and explains basic principle in an easily understandable way (you’ll have to know what XOR does - thats all).
Thanks for the addition of the postfix output - haven’t been that much into mailing for 1.5yrs (used to work for large email service providers back then) - I’m glad that people contribute and check that stuff, it’s really important!
