SETTING PORT EMAIL CANON IRADV
To change the SMTP email port configuration on a Canon imageRUNNER ADVANCE machine, press the physical Settings/Registration button (gear icon) and log in as an administrator. On the touch screen, navigate to Preferences -> Network -> TCP/IP Settings -> SMTP RX/TX Settings. Locate the SMTP TX Port Number field (the default is usually port $25$). Use the on-screen numeric keypad to input your email provider’s required port—such as 587 for STARTTLS or 465 for SSL/TLS encryption. Tap OK to save the changes, and restart the main power switch to apply the new network settings.
