Restricting TextInput to email characters only

Using Flex SDK 4.6, I'm trying to restrict a TextInput field to email characters only as follows:

textInput.restrict = "a-z A-z 0-9 \- _ @ .";

However when I run my application, the TextInput field accepts any character. I'm really not sure why this is not working and would appreciate any help.
