Hello everybody As you know, SMTP is vulnerable to DoS attacks (mail bombing and spamming). You agree also that the solution is PGP or S/MIME. Suppose that you are asked to detect the vulnerabilities of a LAN, how do you proceed to know if the server SMTP is vulnerable to DoS attacks ? In other words, how can you check if this server uses PGP or S/MIME or at least IPsec?
