Well, it's doing exactly what you configured it to do, altough that's 
probably not what you want it to do.

This mean: if the User-Name starts with 1 up to 25 alphabetical 
characters, replace it with that match appended with "@EXAMPLE"

The User-Name does match, because it starts with alphabetical chars. We 
match the "foo" of "foo.bar", that match is stored in the "%{1}" expansion.

Here it performs the expansion and replaces the User-Name with 
"foo at EXAMPLE".

As for how to fix it: I have no idea what you're trying to achieve.
