Recommendation

To ensure the secure delivery of email to the MTA, the Com’X must be updated with the latest available firmware to use current secure email transfer mechanisms. However, this will not guarantee full compatibility with the latest version of the internet email service provider.

Schneider Electric recommends using an on-premise email server (instead of internet email service provider) with a stable and clear security policy defined by the client IT department.

Schneider Electric strongly recommends the use of “TLS/SSL” or “STARTTLS” for the connection security mode between the Com’X and the Email SMTP server. The “None” option is provided only for compatibility with older Email SMTP servers.

Each internet email service provider has its owns security policy and data protection mechanisms to check the sender’s reputation, detect a spam message, etc.
