Setting up the Front SMTP relay

Overview

This article explains how to configure an SMTP relay in Front, so that outbound messages sent from Front, from individual and shared inboxes, are routed through Opensense for signature application.

Before you start

You need:

Front admin access, to configure channel settings
Opensense admin access, to get your relay credentials

Step-by-step guide

Step 1: Get your relay credentials from Opensense

Opensense generates your SMTP relay credentials per domain. You need them to complete the Front configuration.

Sign in to Opensense as an admin.
Go to Manage > Domain Settings > Routing > Relay.
Copy these values. You enter them in Front in the next step.

Host: crm-relay.sendergen.com
Port: 25 or 587. See step 6 in the next section for which to use.
Username: Your domain-specific relay address (for example, yourdomain@sendergen.com)
Password: The generated password shown on this page

Step 2: Configure the SMTP relay in Front

Repeat these steps for each channel (inbox) that should route mail through Opensense.

In Front, go to Settings, and select Workspace for a shared inbox, or Me for an individual inbox.
Select Channels in the left sidebar, and select the channel you want to configure.
Open the channel’s Settings tab.
Under Send Outbound Messages, edit Other SMTP (select Modify).
Enter the relay credentials from Opensense: the host, your username, and your password.
Choose the port, based on your TLS setting:
- 587: if Connect with SSL/TLS encryption is turned on in Front.
- 25: if Connect with SSL/TLS encryption isn’t turned on in Front.
Select Test to check the connection, and then save.
