Simple Mail Transfer Protocol (SMTP) is a text based protocol used for transferring email between mail servers
over the Internet. Typically the local SMTP server will be located on a DMZ so that mail sent by remote SMTP
servers will traverse the router to reach the local server. Local users will then use email client software to retrieve
their email from the local SMTP server. SMTP is also used when clients are sending email and SMTP ALG can be
used to monitor SMTP traffic originating from both clients and servers.
