10.4.1. About SMTP Redundancy
If you create more than one SMTP Server, they can be used in redundancy according to their order in the
list.
You decide to work with redundancy when creating the e-mail recipient (see chapter 12.4).
10.5. POP3 Server
POP3 stands for Post Office Protocol 3. It is used to check and collect e-mails in a mail box.
The POP3 Server represents the mail server used to read mails previously sent to the attention of
TB

.
The use of POP3 is not to retrieve e-mail, but to read the field "Subject" and take some actions.
Two actions can be taken by sending e-mail to TBox:
Alarm acknowledgment sent through e-mail (see next page)
RTU monitoring with predefine message (see chapter 13. ReadSMS/POP3)
The checking of e-mail is generated through an alarm recipient “POP3”.
