Configure SMTP for outbound emails
Configure the IMAP/SMTP settings for your email provider by modifying the following options in the installdir/apps/roundcube/htdocs/config/main.inc.php file. The example below is for Gmail.
// IMAP $config['default_host'] = 'ssl://imap.gmail.com'; $config['default_port'] = 993; // SMTP $config['smtp_server'] = 'tls://smtp.gmail.com'; $config['smtp_port'] = 587;
To configure the application to use other third-party SMTP services for outgoing email, such as SendGrid or Mandrill, 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.
