Regexing AND Email again :-(

[Anon]

$rc2 = (!(ereg("^{[a-z0-9-]+(.[a-z0-9-]+)@([0-9a-z][0-9a-z-][0-9a-z].)+[a-z]{2}[mtgvu]?$",} $erg[1]))) ? 1 : 0;

echo "RC2=$rc2";

When I test "Emailadresse hier eintragen" I get RC2=1.

When I test "[e-mail]" I get RC2=1.

The first one is wrong, but the regex is not so helpfull :-(

Since I can't the regex syntax I need help from a good programmer (or somebody how can make this regex really work)

preg_match("/^{[\S]+@[\S]+.[\S]{2,3}$/",} $string)

Should match one or more non-whitespace characters followed by an '@', followed by one or more non-whitespace characters, followed by a '.', followed by 2 or 3 non-whitespace characters.
