Introduction

This document is a guide to configure a Gmail account as the outgoing Mail Server for 3CX. The configured Gmail account is used to send email notifications, welcome emails and fax messages.

Note: Gmail has a maximum sending restriction of 500 emails per day. An outbound TCP rule for port 587 may be required on some firewalls.

Configuring a Gmail Account as the outgoing Mail Server for 3CX

To configure a Gmail Account as the outgoing Mail Server, follow the steps below:

  1. Access the 3CX Management console and go to Settings > Email
  2. Click on the Mail server tab and fill in the following information (see screenshot above):
  3. Type of Email server: Select Gmail
  4. Gmail username: Enter the Gmail email address
  5. Password: Enter the password for the Gmail account
  6. Click on OK to apply these settings.

To complete this procedure you need to grant access to 3CX to the specified Gmail account for sending emails, as described below.

Grant 3CX Access to the Gmail Account

To grant access to 3CX to sending email via a Gmail account:

  1. Sign in to the Gmail account.
  2. Click on the Google Apps link on the top right hand corner
  3. Click on the Account icon. If you cannot see it, click on More to find it.

  1. In the Sign in and security section, click on Apps with account access (see Fig. 2 above).

  1. Scroll down and set Allow less secure apps to ON (see Fig. 3 above).

Troubleshooting 3CX Access to a Gmail Account

In some cases, it is required to login to Gmail at least once from the 3CX Server host for verification purposes. To do this open a browser on the machine hosting the 3CX system, go to https://gmail.com and authenticate with your credentials.

After the above step, Gmail has in its records a verified authentication for this account from the 3CX host.
