How To Catch An Error Raised In The Forach Loop Container And Perform Cleanup Jobs Accordingly?

Hello everyone,

I have a package that should accomplish the following task:
- Loop on all files in a given directory.
- Before proccessing the current file in the Enumerator, it should be moved to a folder called "importing"
- Load the content of the file into a destination DB.
- After a successfull load, the file is moved from the "importing" to the "success" folder.
- If anything went wrong during the load process, the file should be moved from the "importing" to the "error" folder and an e-mail should be sent out to a certain admin account.

What I have done so far:
My control flow looks like this:
Foreach Loop containing the following tasks:
- File System Task: moving the current file from its original path to the "importing" folder
- Data Flow Task1: performing some transformations and insertions into the DB and raw files.
- Data Flow Task2: performing some transformations and insertions into the DB and raw files.
- Data Flow Task3: performing some transformations and final insertions into the DB.
- File System Task: moving the current file from the "importing" to the "success" folder

Question:
I do not know how to catch the event that one of my three Data Flow Tasks has failed and in this case perform two simple tasks, namely...
- File System Task: moving the current file from the "importing" to the "error" folder
- Send Mail Task: sending a configured e-mail message to a ceratin administrator.

Thanks in advance...
