On this topic
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:
- Access the 3CX Management console and go to “Settings” > “Email”
- Click on the Mail server tab and fill in the following information (see screenshot above):
- “Type of Email server”: Select “Gmail”
- “Gmail username”: Enter the Gmail email address
- “Password”: Enter the password for the Gmail account
- 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:
- Sign in to the Gmail account.
- Click on the Google Apps link on the top right hand corner
- Click on the “Account” icon. If you cannot see it, click on “More” to find it.
- In the “Sign in and security” section, click on “Apps with account access” (see Fig. 2 above).
- 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.
