Getting email of sender: reliable code

Question

I am trying to get a reliable way to find the email address of the sender into a string. The code below will get me the email address that I want, but it seems like a lot of work to do just that. I am surprised that their is not a message.getFromAddress() or message.getEmailAddress(), etc. Let me know if you think that this is a reliable way to get the sender email address. The code works for all instances that I have tried it on.
Address[] addressArray = message.getFrom();
Address someAddress = addressArray[0];
String someAddressString = someAddress.toString();
String email = findEmail(someAddressString);
public static String findEmail(String email) {     
String validEmailReg = "[^A-Za-z0-9\\.\\@_\\-~#]+";
Pattern arrayString = Pattern.compile("[,\\s]+");
          Pattern badChar = Pattern.compile(validEmailReg);
          Pattern brackets = Pattern.compile("<");
          StringBuffer sb = new StringBuffer();
          boolean deletedIllegalChars = false;
     // Split input with the pattern.
          String[] result = arrayString.split(email);
          for (int i = 0; i < result.length; i++) {
               Matcher bracketsM = brackets.matcher(result);
               // try and find the <[email protected]>
               if (bracketsM.find()) {
                    bracketsM = badChar.matcher(result[i]);
                    boolean badCharResult = bracketsM.find();
                    // got the email address. No remove the <>
                    while (badCharResult) {
                         deletedIllegalChars = true;
                         bracketsM.appendReplacement(sb, "");
                         badCharResult = bracketsM.find();
                    bracketsM.appendTail(sb);
                    email = sb.toString();
          return email;

The easy way to do this is to pass the header to an InternetHeaders object. You then have methods like getAllHeaders() to return an Enumeration of the headers and getHeader(String name) to retrieve the value you want.
