20.0 SMTP (Simple Mail Transfer Protocol)
SMTP (RFC 821) is a TCP/IP protocol used in sending e-mail. However, since it’s limited in its
ability to queue messages at the receiving end, it’s usually used with one of two other protocols,
POP3 or Internet Message Access Protocol that let the user save messages in a server mailbox and
download them periodically from the server. In other words, users typically use a program that uses
SMTP for sending e-mail and either POP3 or IMAP for receiving messages that have been received
for them at their local server.
SMTP is implemented to operate over Transmission Control Protocol (TCP) port 25. The details of
SMTP are in Request for Comments 821 of the Internet Engineering Task Force (IETF).
In LE2425A and LEV2525A switches, SMTP is used to send email alerts whenever there is an event
or an SNMP trap generated inside the switch system.
Send email alert according to the configuration rules when a specific event category happens

happens
