Send email from a printer, scanner, or app

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

This article is for G Suite administrators. If you're not an admin and you're trying to send an email from a device or app, ask your G Suite admin for help.

You can set up your on-premises printer, scanner, fax, or app to send email through G Suite using:

  • G Suite SMTP relay service (recommended)
  • Gmail SMTP server
  • Restricted Gmail SMTP server

Note: SMTP relay service is only available for G Suite editions.

Step 1: Choose your configuration option

Depending on what's supported by your device or app, you can choose one of the following configuration options.

G Suite SMTP relay service

Use the SMTP relay service to send mail from your organization by authenticating with IP addresses. You can send messages to anyone inside or outside of your organization. This option is the most secure.

Requirements

Sending limits

A G Suite user can relay messages to up to 10,000 recipients per day. 

See: Sending limits for the SMTP relay service
Anti-spam filters Suspicious emails might be filtered or rejected.
Fully qualified domain name of SMTP service smtp-relay.gmail.com
Configuration options

  • Port 25, 465, or 587

  • Secure Socket Layer (SSL)/Transport Layer Security (TLS) protocols.

  • Dynamic IPs are allowed, but a static IP might be required due to authentication requirements.

See: SSL connections overview
Authentication requirements

Static IP address or a valid G Suite user sign-in.
Gmail SMTP Server requirements

You can send mail to anyone inside or outside of your organization. This option requires you to authenticate with your Gmail or G Suite account and password. 

Requirements

Sending limits

2,000 messages per day. 

See: Email sending limits
Anti-spam filters Suspicious emails might be filtered or rejected.
Fully qualified domain name of SMTP service smtp.gmail.com

Allows you to send messages to Gmail or G Suite users only. This option does not require you to authenticate. 

Requirements

Sending limits Per-user limits apply. This option restricts sending messages to only Gmail or G Suite users.
Anti-spam filters Suspicious emails might be filtered or rejected.
Fully qualified domain name of SMTP service aspmx.l.google.com
Configuration options

  • Port 25

  • TLS not required

  • Dynamic IPs allowed 

  • Can only send to Gmail or G Suite users
Authentication requirements None

Step 2: Set up your device or app to send email

G Suite support cannot assist with configuration settings. For help with setup, refer to your device or app's documentation.

To set up your device or app to send email using Gmail servers, follow the steps for the option you chose in step 1.

Set up G Suite SMTP relay in the Admin console
  1. Sign in to your Google Admin console.

    Sign in using your administrator account (does not end in @gmail.com).

  2. From the Admin console Home page, go to Appsand thenG Suiteand thenGmailand thenAdvanced settings.

    Tip: To see Advanced settings, scroll to the bottom of the Gmail page.

  3. Next to SMTP relay service, click Configure.
  4. Set up the SMTP relay service.
    See: SMTP relay: Route outgoing non-Gmail messages through Google
  5. On your device or in your app, on port 25, 465, or 587, connect to smtp-relay.gmail.com.
Use the Gmail SMTP Server

If you connect using Secure Sockets Layer (SSL) or Transport Layer Security (TLS), you can send mail to anyone if you use smtp.gmail.com as your server.

Before you begin (recommended): If you use 2-step verification and the device or app doesn't accept verification codes, set up App Passwords for the desired account. For details, see Sign in using App Passwords. 

  1. Enter smtp.gmail.com as the server address.
  2. In the Port field, enter one of the following numbers:
    • If you're using SSL, enter 465.
    • If you're using TLS, enter 587.
  3. For authentication, enter your full G Suite or Gmail address (you@example.com) and password. Make sure to sign in to the account before you use it with the device or app.
Use the restricted Gmail SMTP Server

If your device or app doesn't support SSL, you can only send mail to Gmail or G Suite users. And, you'll need to use the restricted SMTP server aspmx.l.google.com.

  1. On your device or app, connect to the restricted SMTP server:
    1. Enter aspmx.l.google.com as the server address.
    2. In the Port field, enter 25.
  2. In your Google Admin console, add the IP address of the device or app to the email whitelist. For details, see Whitelist IP addresses in Gmail.
  3. Set up an SPF record for your domain with the IP address of the device or app so that recipients don’t reject mail sent from it.

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

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

    For details, see Help prevent email spoofing with SPF records.

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