Network Functions in the Operator Panel
276 Mitsubishi Electric, MA00759F
19.2 SMTP Client
SMTP (Simple Mail Transfer Protocol) is a TCP/IP protocol used to send and receive
e-mail. Since SMTP has limited functions to store received messages it is normally
used together with one or two other protocols, POP3 or IMAP. These protocols allow
the user to save messages in a server mailbox from where they can be collected later.
This means that SMTP is normally used to send e-mail, and POP3 or IMAP to re-
ceive messages stored in the local server. The operator panel can function as an SMTP
client, i.e. send e-mail. To use the SMTP client function it is necessary to have access
to an e-mail server. You can use your Internet provider’s e-mail server, or use a local
e-mail server. See also the section Network Services in the chapter Network Commu-
nication.
