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 3CX outgoing Mail Server

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).

Configuration to Mail server in VoipTools

Once you have configured Gmail details in 3CX Management Console, you should also configure the same credentials in our application E-mail settings. To configure email settings in our application, follow the steps below:

1. Open the application, and go to “Email Settings” Under Mail Server: Enter the Server/smarthost, IP address or Fully Qualified Domain Name (FQDN) of your email server.

  For Gmail:-

  SMTP Port: Default port number is 25. For Gmail / Google Apps use Port 587 (recommended) or port 25

 Requires Authentication:

Check this option if your mail server requires authentication to relay emails. Enter the sign-in credentials of the hosted mailbox being used in 3CX Management Console>Settings>Email.

SSL / TLS: Select this option if your mail server requires a secure connection -- Secure Socket Layer (SSL) or Transport Layer Security (TLS) to relay email. Gmail, Google Apps, and Office 365 require a secure connection.
Tip:   Sending mail within your domain may not require authentication, while sending outside your domain may require authentication.
