I've never been happy with the regular expression matching functions in CF. Hence, I wrote my own:

    function reFindNoSuck(string pattern, string data, numeric startPos = 1){
        var sucky = refindNoCase(pattern, data, startPos, true);
        var i = 0;
        var awesome = [];

        if (not isArray(sucky.len) or arrayLen(sucky.len) eq 0){return [];} //handle no match at all
        for(i=1; i<= arrayLen(sucky.len); i++){
            //if there's a match with pos 0 & length 0, that means the mime type was not specified
            if (sucky.len[i] gt 0 && sucky.pos[i] gt 0){
                //don't include the group that matches the entire pattern
                var matchBody = mid( data, sucky.pos[i], sucky.len[i]);
                if (matchBody neq arguments.data){
                    arrayAppend( awesome, matchBody );
                }
            }
        }
        return awesome;
    }

Applied to your problem, here is my example:

Dumping the "matches" variable shows that it is an array with 2 items. The first will be (because it matches the entire regex) and the second will be joesmith@domain.com (because it matches the 1st group defined in the regular expression -- all subsequent groups would also be captured and included in the array).
