Configure SMTP for outbound emails

Google Cloud Platform doesn’t allow SMTP traffic through default ports: 25, 465, 587. Check Google cloud documentation to learn how to use a VPN to bypass these restrictions or use a different port for sending emails from your application.

Configure the SMTP settings for the email provider by modifying the file /opt/bitnami/apps/testlink/htdocs/ (or by creating it if it does not exist).

Here is an example of using this file to configure TestLink to use a Gmail account. Replace USERNAME and PASSWORD with your Gmail account username and password respectively.


$g_smtp_host = '';

$g_tl_admin_email = '';
$g_from_email = '';
$g_return_path_email = '';

$g_smtp_username = '';
$g_smtp_password = 'PASSWORD';

$g_smtp_port = '587';
$g_smtp_connection_mode = 'tls';


Save the file and restart the services:

$ sudo /opt/bitnami/ restart

To configure the application to use other third-party SMTP services for outgoing email, such as SendGrid, refer to the FAQ.

NOTE: If you are using Gmail as the outbound email server and have experienced issues trying to send emails correctly, check the Gmail SMTP troubleshooting page to learn the causes of these issues and how to solve them.
