Configure SMTP for outbound emails
NOTE: The Approach A sections referred to below do not apply to Bitnami native installers. Users of Bitnami native installers should refer only to the Approach B sections.
Configure the IMAP/SMTP settings for your email provider by modifying the following options in the RoundCube configuration file. Depending on your installation type, it will be located in one of the following paths:
Approach A (Bitnami installations using system packages): installdir/roundcube/config/config.inc.php
Approach B (Self-contained Bitnami installations): installdir/apps/roundcube/htdocs/config/config.inc.php
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, 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.
