Fast answer in No.
But, you may do it by using SSO functionality
<?php // Enable RainLoop Api and include index file $_ENV['RAINLOOP_INCLUDE_AS_API'] = true; include '/var/www/rainloop/index.php'; $ssoHash = \RainLoop\Api::GetUserSsoHash('firstname.lastname@example.org', 'super-password', array( 'Language' => 'ru_RU' )); // redirect to webmail sso url \header('Location: http://yourdomain.com/rainloop/?sso&hash='.$ssoHash);
Unfortunately. it doesn't work right now (additional language parameter), but it will be fixed in the next version.
