Load the data into a string (I'm using $str for that) and apply a email regular expression:

$pattern = '/[A-Z0-9._%+-]+@[^\.].*\.[a-z]{2,}/i';
if (preg_match($pattern, $str, $matches)){
    echo $matches[1];
}

As Guy commented below, you can load the file into a string with:

$str = file_get_contents('/path/to/file');

EDIT:

For hotmail, you can change the pattern to:

$pattern = '/[A-Z0-9._%+-]+@hotmail.com/i';

Just pin point the fact that you can get the `$str` with `$str = file_get_contents('/path/to/file');` – gmaliar Jul 09 '13 at 07:47
