Configure SMTP for outbound emails

Configure the SMTP settings by modifying the file /opt/bitnami/apps/typo3/htdocs/public/typo3/sysext/core/Configuration/DefaultConfiguration.php.

For example, these are the options to configure it using a Gmail account. Replace USERNAME and PASSWORD with your Gmail account username and password respectively, and NAME with the sender name.

'transport' => 'smtp',
'transport_smtp_server' => 'your.smtp.provider:PORT',
'transport_smtp_encrypt' => 'TLS_OR_SSL',
'transport_smtp_username' => 'USERNAME@gmail.com',
'transport_smtp_password' => 'PASSWORD',
'transport_sendmail_command' => '',
'defaultMailFromAddress' => 'USERNAME@gmail.com',
'defaultMailFromName' => 'NAME',

Restart the server for your changes to take effect:

$ 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.
