Read mail from stdin and test

spamtrap reads spam from stdin. It locates any IP addresses in the spam and tests them using relaytest(1), httptest(1), socks4test(1), socks5test(1), and formmailtest(1). If any of these IP addresses are open to relaying, they will be added to the DSBL-compliant server that these programs are configured to use.
