Description

The event notification is used to send emails when the wireless devices trigger an alarm. The alarms are configured by the administrator and can be sent to many users.

Prerequisite

Consult the administrator to get the right IT connection to access the port, Internet, and e-mail server.

Principle

Step	Action
1	The PowerTag Link gateway sends an email to the configured email server / MTA (Mail Transfer Agent) using SMTP protocol.
2	MTA forwards the message to the email client MDA (Mail Delivery Agent).
3	MDA delivers email to the client/ MUA (Mail User Agent) using POP3 or IMAP protocol.

Recommendations

To ensure secure delivery of the email to the MTA, the PowerTag Link gateway must be updated to the last available firmware to use recent security email transfer mechanisms. However, this will not guarantee a full compatibility with the latest version of Internet email service provider. Schneider Electric is not liable for these policies and their impact in email deliverability.
When possible, Schneider Electric recommends using an on-premise email server (instead of Internet email service provider) with stable and clear security policy defined by the client IT department.

Schneider Electric recommends selecting TLS/SSL or STARTTLS for the connection security mode between the PowerTag Link gateway and the Email SMTP server. Consequently, it is recommended to use an Email SMTP server that supports at least one of these two modes. The None option is provided only for compatibility with older Email SMTP servers. Since the None option does not provide a secure communication, its usage is not recommended and should be avoided.

WARNING
POTENTIAL COMPROMISE OF SYSTEM AVAILABILITY, INTEGRITY, AND CONFIDENTIALITY Use TLS 1.2 for email notification encryption. Failure to follow these instructions can result in death, serious injury, or equipment damage.

To secure your email from sniffing, verify that your email server supports TLS 1.2. Under certain circumstances, notifications can be sent using SSL, TLS 1.0, or TLS 1.1. However, this is not recommended.
Each Internet email service provider has it owns security policy and data protection mechanisms to check sender’s reputation, detect spam message, and so on. Schneider Electric is not liable for these policies and their impact in email deliverability.
