To just extract the email address out of an RFC822 line, it's faster and more reliable to just use a simple regex such as:

<?php
$rfc 
'"Bob Smith" <bob@smith.com>';
preg_match('/[\\w\\.\\-+=*_]*@[\\w\\.\\-+=*_]*/'$rfc $regs);
$parsed $regs[0];
?>

The above code will pull out: bob@smith.com

No matter the variation of the RFC822 line, as long as there's a valid email address in it somewhere, the above regex will find it.

An alternative to the mailparse_rfc822_parse_addresses() function is Mail_RFC822::parseAddressList() from Pear:
http://pear.php.net/manual/en/package.mail.mail.php
It parses the string and returns a structured tree of data. Returns a pear_error object if the string is not valid.
Example:
require_once "PEAR.php";
require_once "Mail/RFC822.php";

$addr= "Hi <hi@world.org>";

$res= Mail_RFC822::parseAddressList($addr);
if (PEAR::isError($res)) die("NOT VALID: " . $res->getMessage() . "\n");
echo "OK. Data:\n";
print_r($res);

If for some reason you cannot compile mailparse into your install of PHP, you will also find an extremely similar function in the Mail_MIME PEAR class, specifically in mimeDecode.php.
