ResumoElectronic mail (e-mail) is one of the most popular network services nowadays. Most e-mail systems that send mail over the Internet use simple mail transfer protocol (SMTP) to send messages from one server to another. The messages can then be retrieved with an e-mail client using either post office protocol (POP) or Internet message access protocol (IMAP). SMTP is also generally used to send messages from a mail client to a mail server in “hostbased” (or Unix-based) mail systems, where a simple mbox utility might be on the same system [or via Network File System (NFS) provided by Novell for access without POP or IMAP. SMTP is used as the common mechanism for transporting electronic mail among different hosts within the transmission control protocol/Internet protocol (TCP/IP) suite. It is an application layer protocol. With the increase of electronic communication, spams are widely increased targeting individuals, having a doubtful intension such as stealing personal information to be misused or even to paralyze the event system by injecting viruses. Therefore, to protect email users from spams and viruses, it is crucial to protect our SMTP servers .
