Email

Use the Email plug-in to configure outgoing mail servers for sending messages from the OPC Router. The actual sending logic is handled later in the Email Transfer Object within a flow.

Receiving emails is set up separately using the Email Trigger. This ensures that sending and trigger activation remain clearly separated from a technical standpoint.

If you only want to send emails, you generally only need the Email Plug-in and an Email Transfer Object. You only need the Email Trigger if incoming emails are to trigger a flow.

If there is a firewall between OPC Router and the mail server, open the necessary ports for the connection.

Scope of Use​

  • The Email Plug-in configures the SMTP server for sending emails.
  • The Email Transfer Object creates and sends emails within a flow.
  • The Email Trigger monitors a mailbox within a flow and triggers data transfer when emails are received.

Configuration​

  1. Open the Email section in the Plug-ins.
  2. Click Plus to create a new mail server, or open an existing entry.
