Email reception (POP3/IMAP)

An email inbox – and therefore a dedicated mailbox for the visual energy system – is currently only required if MSCONS data are to be retrieved from a market participant.

Protocol	POP3 or IMAP
Hostname	A URL that points to the server. Example: “smtp.visualenergy.de”. This URL must be accessible from the visual energy system.
Port	The port number on which the server can be reached. Typical ports: SMTP (unencrypted): Port 25. SMTP (with TLS transport encryption): Port 587
Transport encryption	None – Transport encryption is not used. Auto – The client and server negotiate the security settings. StartTLS – The connection is initially established in unencrypted plain text and only switches to encrypted communication afterwards. SSL / TLS – Encrypted communication between client and server.
Trust all certificates	Self-signed certificates are often used, particularly in internal company applications. However, this means that it is not possible to establish a clear chain of trust back to a root certificate, and therefore the trust relationship cannot be established. You should therefore enable this option by selecting YES to trust these certificates as well, or select NO if only officially valid certificates are used.
Username	Valid account if “Authentication required” is set to “YES”.
Password	Valid password
Delete messages	Deletes the retrieved emails from the server after they have been downloaded (IMAP only)
