Configure SMTP for outbound emails
This is required so the application can send notifications via email.
Edit the installdir/apps/owncloud/htdocs/config/config.php and add the following at the end of the file. This example uses a Gmail account. Replace USERNAME and PASSWORD with your Gmail account username and password respectively.
... "mail_smtpmode" => 'smtp', "mail_smtphost" => 'ssl://smtp.gmail.com', "mail_smtpport" => 465, "mail_smtpauth" => true, "mail_smtpname" => 'USERNAME@gmail.com', "mail_smtppassword" => 'PASSWORD', ); ?>
NOTE: Configure the administrator email from the ownCloud admin panel under the “Settings -> Personal -> Email” menu.
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.
