This article describes how to configure your Google Workspace Admin Console to support WiseStamp’s Server-side solution. The configuration is done in the following sequential phases:
- Adding a New Mail Host to serve as the outbound connector to the WiseStamp Server-side host
- Configuring the SMTP Relay Service to set up routing for the inbound connector
- Configuring a Compliance Rule to ensure that emails are routed to WiseStamp Server-side host
- Performing a Validity Check by sending a test email and establishing the server connection
Additional steps for enhancing efficiency and security are presented in the Post Configuration Procedures section.
All procedures are performed from the Google Workspace Admin Console. To get started, log in and navigate to Apps > Google Workspace > Gmail.
Adding a New Mail Host
The first phase of the configuration involves adding a mail host. This host acts as an outbound connector to allow your emails to route to WiseStamp’s Server-side signatures.
Before you begin, make sure you have access to the routing code provided by WiseStamp. You will need it during the configuration. To locate your unique code, navigate to the left-side menu and click on Integrations, then select Connect to Google Workspace. This action will trigger a pop-up window to appear, which will display your unique code. You can refer to the accompanying screenshot for guidance:
To add a mail host:
Under Settings for Gmail, expand the Hosts pane.
Then, click Add Route.
At the top of the popup that opens, enter a name for the new host (e.g., WiseStamp).
- Configure the following settings:
- Under Specify email server, verify that Single host is selected from the dropdown list.
- In the field below, enter your routing code followed by .gw.smtp.wisestamp.net
For example: 2gg2mrqnl6nlx.gw.smtp.wisestamp.net
- Enter 25 as the port number for the host configuration.
- Under Options, select all checkboxes except for Perform MX lookup on host.
- At the bottom of the popup, click Save.
Configuring the SMTP Relay Service
This phase involves configuring routing for the inbound connector to receive the email back from the WiseStamp server.
To configure the SMTP relay service:
Under Settings for Gmail (Apps > Google Workspace > Gmail), expand the Routing pane.
Then, under SMTP relay service, click Configure.
- At the top of the popup that opens, enter a description for the service (e.g., Receive from WiseStamp).
From the Allowed Senders list, select Only addresses in my domains.
Configure authentication settings:
a. Under Authentication, select the Only accept mail from the specified IP addresses checkbox.
Then, click Add.
b. At the top of the popup that opens, enter a meaningful description (e.g., WiseStamp).
c. In the field below, enter the following IP: 18.104.22.168
d. Verify that the Enable checkbox is selected.
e. Click Save.
Under Encryption, select the Require TLS Encryption checkbox.
Configuring the Compliance Rule
The final stage of the configuration involves creating a compliance rule to ensure that your emails are routed to your WiseStamp Server-side host.
Before you begin, make sure you have access to the routing code provided by WiseStamp. You will need it during the configuration.
To configure the compliance rule:
Under Settings for Gmail, expand the Compliance pane.
Then, under Content compliance, click Configure.
At the top of the dialog that opens, enter a description for the rule (e.g., Route WiseStamp).
- Under Email messages to affect, select the following checkboxes:
- Internal – Sending
Under Expressions, click Add.
- In the popup that opens, select Advanced content match from the dropdown list.
- Configure the following settings:
- Location: Select Full headers.
- Match type: Select Not contains text.
- Content: Enter X-WiseStampHostedSignatures-MessageProcessed
- Click Save.
From the dropdown list under If the above expressions match, select Modify message. Then, under Headers, select the Add custom headers checkbox and click Add.
- In the pane that opens, create a header with the following parameters:
- Header key ( X- ): Enter the following text: Wisestamphostedsignatures-Auth
Header value ( : ): Paste the WiseStamp routing code here
Then, click Save.
Under Route, select the Change route checkbox.
Then, from the Normal Routing dropdown list, select the outbound connector route that you created earlier.
Under Encryption (onward delivery only), select the Require secure transport (TLS) checkbox.
Performing a Validity Check
After configuring the required connectors and rules, go back to WiseStamp to test your settings and complete the setup.
To test connections and set up your environment:
- Send a test email to yourself or a colleague, and verify that the WiseStamp signature displays as expected.
NOTE: The signature will be displayed only on messages that are received by you or your colleague. WiseStamp signatures will NOT appear in items in your Sent folder.
- From the Connectors page, click Connect.
- IMPORTANT: Make sure that several selected people in your organization have access to the login credentials for the Google Admin Console. Quick access to the admin console is critical for rapid troubleshooting if email delivery becomes interrupted.
Post Configuration Procedures
The following sections describe additional procedures that should be done to help ensure maximum efficiency and security.
Setting Up Devices and Apps
We recommend using the SMTP relay service to send emails from devices or apps. For complete details on how to set up your devices and apps to send email through Google Workspace using the service you configured (Configuring the SMTP Relay Service), refer to the instructions in Option 1 of this article.
Configuring Your SPF Record
For protection against spoofing and phishing and to help prevent your messages from being marked as spam, we recommend adding Sender Policy Framework (SPF) records to your domain. For details about SPF management, please refer to this article.
In the event that new outgoing emails are not being sent or are being rejected, it is recommended to disable the compliance rule in the Google Workspace Admin Console until the source of the interruption is identified.
To disable the compliance rule:
- Log into the Google Workspace Admin Console and navigate to Apps > Google Workspace > Settings for Gmail > Compliance.
- Under Content compliance, in the row of the rule you created for Wisestamp, click Disable.
