Configure SMTP for outbound emails

To manually configure the email settings for Multicraft, follow these steps:

  • Edit the /opt/bitnami/apps/multicraft/htdocs/protected/config/internal/application.php file and look for the uncommented transportOptions section.

  • Update this to reflect your SMTP server details. For instance, for a Gmail configuration, it would look something like this. Replace USERNAME and PASSWORD with your Gmail account username and password respectively.

    'transportOptions' => array(
        'host' => '',
        'username' => '',
        'password' => 'PASSWORD',
        'port' => '587',
        'encryption' => 'tls',
  • Make sure that the transportType variable is set to “smtp”.

After this, Multicraft should be configured to send emails. You can also visit the Multicraft administration panel to update your mail preferences.

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.
