Path: Security > Firewall > ALGs > SMTP ALGs
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 the mail sent by remote SMTP
servers will traverse the controller 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 trac originating from both clients and servers.
1. Click Security > Firewall > ALGs > SMTP ALGs tab.
