Configure SMTP for outbound emails
NOTE: We are in the process of modifying the file structure and configuration for many Bitnami stacks. On account of these changes, the file paths stated in this guide may change depending on whether your Bitnami stack uses native Linux system packages (Approach A), or if it is a self-contained installation (Approach B). To identify your Bitnami installation type and what approach to follow, run the command below:
$ test ! -f "/opt/bitnami/common/bin/openssl" && echo "Approach A: Using system packages." || echo "Approach B: Self-contained installation."
The output of the command indicates which approach (A or B) is used by the installation, and will allow you to identify the paths, configuration and commands to use in this guide. Refer to the FAQ for more information on these changes.
: Google Cloud Platform doesn’t allow SMTP traffic through port 25. Check Google cloud documentation to learn how to use a different port for sending emails from your application.
Configure the SMTP settings for the email provider by modifying the custom_config.inc.php configuration file (or by creating it if it does not exist).
NOTE: Depending on your installation type, the custom_config.inc.php configuration file will be in one of the following locations:
Approach A (Bitnami installations using system packages): /opt/bitnami/testlink/custom_config.inc.php
Approach B (Self-contained Bitnami installations): /opt/bitnami/apps/testlink/htdocs/custom_config.inc.php
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.
<?php $g_smtp_host = 'smtp.gmail.com'; $g_tl_admin_email = 'USERNAME@gmail.com'; $g_from_email = 'USERNAME@gmail.com'; $g_return_path_email = 'USERNAME@gmail.com'; $g_smtp_username = 'USERNAME@gmail.com'; $g_smtp_password = 'PASSWORD'; $g_smtp_port = '587'; $g_smtp_connection_mode = 'tls'; ?>
Save the file and restart the services:
$ sudo /opt/bitnami/ctlscript.sh 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, your application’s attempts to send outgoing emails may be blocked by Gmail if it considers the authentication attempts to be suspicious. When this happens, you will receive a Gmail security alert at the corresponding Gmail address. To proceed, you will need to manually confirm the validity of the authentication attempt before Gmail will permit the application to send outbound emails. For more information on this and other Gmail issues related to outbound email from your application, refer to our Gmail SMTP troubleshooting page.
