Looks like you're using RoundCube on a PHP installation with safe_mode enabled. When RoundCube is configured to use PHP's mail() function there maybe restrictions like the one you described. Try to configure an SMTP server in config/main.inc.php get around the PHP mail() functions.

I'm using v0.1-beta2 and I'm having a problem with the 'Sender' in the mail headers that are sent from Roundcube.
The Sender field is always set to 'www-data@myserver.com', but X-Sender is set to the senders email address (which I believe is correct). Is there any way to tell Roundcube/PHP not to set the 'Sender' in the mail header ?
Thanks
