I have a requirement to send a common email to 20000 users from our application. I want to schedule a batch that reads the user email id from a file/table and sends the email.

Is there any way to track whether the email is sent successfuly other than catching the exception.

Is there any open source library that handles the bulk emailing.


Thanks
