Today, 13th Friday, I’ve updated and released a new version of my Nmap NSE script «SMTP Open Relay Test». Grab it from HERE.
It will run a series of tests against SOME_HOST, using service detection (-sV) on the standard ports (-F), then run the script SMTP_openrelay_test.lua against those ports that have a running smtp service. Later on it will let you know the results 😉
Hope you enjoy it. At least I did. I found out that almsot 50% of .edu.ar’s mailservers are open relays (yeah, I reported that!). Too bad they didn’t do anything.
I’ve also updated the HTTP Open Proxy test script. Read about it here.
