3. order status emails are being send fine

2. send a message

Expected result (*)

1. email is sent

Actual result (*) 1**. as a user get a generic error message that email could not be sent** 2. No log entry in any of the Magento, PHP or Apache logs that provides any insight

Since order status emails can be sent, Magento is clearly capable of sending emails to users. At the very least, there must be a log entry THAT something happend and best even provide inside what needs fixing. Currently there is no log entry at all. Not even on DEBUG level.
