# Configure Canon Printers for Scan to Email with mySMTP

> Set up Scan to Email on Canon imageRUNNER and imageRUNNER ADVANCE printers via Remote UI. Enter mySMTP relay, port 587, and SMTP authentication details.

## SMTP settings

| Setting | Value |
| - | - |
| Server (dedicated) | `relayxx.mysmtp.com` (from your setup email) |
| Server (shared IP, DK only) | `mail.mysmtp.com` |
| Port | **587** |
| Encryption | STARTTLS |
| Authentication | SMTP authentication with your mySMTP username and password |
| From address | An address on your authenticated domain |

<Note>
  Shared IP plans are only available to customers in Denmark.
</Note>

## Set up Scan to Email on imageRUNNER / imageRUNNER ADVANCE

<Steps>
  <Step title="Open the Remote UI">
    Find the printer IP address on the device control panel or by printing a network settings page. Enter the IP in a browser (for example, `http://192.168.1.50`). Log in as an administrator if required.
  </Step>

  <Step title="Navigate to email settings">
    Go to **Settings/Registration** > **Send** > **E-mail/I-Fax Settings**. On some models the path is **Network Settings** > **E-mail Settings**.
  </Step>

  <Step title="Enter the SMTP server">
    In the **SMTP Server** field, enter your mySMTP relay hostname (for example, `relayxx.mysmtp.com`). Set the port to **587**.
  </Step>

  <Step title="Enable SMTP authentication">
    Turn on **SMTP Authentication** and enter your mySMTP username and password.
  </Step>

  <Step title="Configure TLS">
    Enable **Use TLS for SMTP** or **SMTP TX (TLS)** if the option is available. Do not enable **POP before SMTP**.
  </Step>

  <Step title="Set the sender address">
    In the **From Address** or **Default Sender** field, enter an email address that uses a domain authenticated on your mySMTP account.
  </Step>

  <Step title="Save and test">
    Save the settings and send a test scan to your own email address. Check your inbox and spam folder.
  </Step>
</Steps>

<Warning>
  Do not enable **POP before SMTP** on Canon devices. mySMTP uses SMTP authentication, not POP authentication.
</Warning>

## PIXMA and MAXIFY note

PIXMA and MAXIFY all-in-one printers do not always expose full SMTP settings in the Remote UI. Some models require you to use the IJ Scan Utility or Canon PRINT app to scan to a file and then send it manually. If your PIXMA or MAXIFY printer does offer Scan to Email in the EWS, apply the same server and authentication settings listed above.

## Troubleshooting

<AccordionGroup>
  <Accordion title="TLS error on port 587">
    Older Canon firmware may not support STARTTLS. Switch to port **2525** and disable TLS. Check Canon’s support site for a firmware update.
  </Accordion>

  <Accordion title="Authentication failed">
    Re-enter your mySMTP username and password. Do not enable POP before SMTP.
  </Accordion>

  <Accordion title="Relay access denied">
    Confirm the **From Address** uses a domain authenticated on your mySMTP account.
  </Accordion>

  <Accordion title="Scan file is too large">
    Reduce the resolution or use black-and-white scanning to keep the file under the attachment size limit. See [Email Attachments Size](/troubleshooting/email-attachments-size).
