Send email from a printer, scanner, or app

Use G Suite settings to set up a device or app to send email

You can set up your on-premises printer, scanner, fax, or application to send email through G Suite. Depending on your requirements, the available options are:

  • G Suite SMTP relay service—Send mail from your organization by authenticating with the IP addresses. You can send messages to anyone inside or outside of your domain.
  • Gmail SMTP server—Send mail to anyone inside or outside of your domain. This option requires you to authenticate with your Gmail or G Suite account and password. 
  • Restricted Gmail SMTP server—Send messages to Gmail or G Suite users only. This option does not require you to authenticate.

Note: Our support team can't assist with configuration settings. For details about configuring your device or application to send SMTP messages, refer to its respective documentation.

Step 1: Choose your configuration option

Open all  |  Close all

The following are the configuration options based on what’s supported by your device or application. You configure these options within the device or application.

Step 2: Send mail from your device or application

Open all  |  Close all

To send mail from your device or application using Gmail servers, follow the steps for the option you chose.

Set up G Suite SMTP relay in the Admin console (recommended)

To use the G Suite SMTP relay (recommended and most secure setup option):

  1. From the Admin console, click Apps and then G Suite and then Gmail and then Advanced settings.
  2. Add your network IP range to the SMTP relay service.
  3. Configure your device to connect to smtp-relay.gmail.com on port 25, 465, or 587.

For more details about using this setting, see SMTP relay service setting.

Use the Gmail SMTP Server

If you connect using SSL or TLS, you can send mail to anyone with smtp.gmail.com

Note: Before you start the configuration, we recommend you set up App passwords for the the desired account. 

  1. Connect to smtp.gmail.com on port 465, if you’re using SSL. (Connect on port 587 if you’re using TLS.)
  2. Sign in with a Google username and password for authentication to connect with SSL or TLS.
  3. Ensure that the username you use has cleared the CAPTCHA word verification test that appears when you first sign in.

Use the restricted Gmail SMTP Server

If your device or application doesn’t support SSL, you can only send mail to Gmail or G Suite users.

Use the restricted SMTP server aspmx.l.google.com.

  1. Connect to aspmx.l.google.com on port 25.
  2. In your Google Admin console, add the IP address of the device or application to the email whitelist.
  3. Set up an SPF record for your domain with the IP address of the device or application so that recipients don’t reject mail sent from it.

For example, if your sending device sends from 123.45.67.89, add that address to your SPF record without removing the G Suite mail servers from the record:

v=spf1 ip4:123.45.67.89 include:_spf.google.com ~all.

Tip: To test your SPF record, use the G Suite toolbox.
