Everything I know about regex could be written on the head of a pin, but I do have a working snippet that should be adaptable ...

[code]        if (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)) {
            $err.= $email. " is not a valid email address.<br/>";
}[/code]

here's another option that should be adaptable:
[code]
<?php
$email = "<a href=\"mailto:[email protected]\">email address</a>";
if (!preg_match('|^<a.+?([A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}).+?\>([a-z0-9 ]{1,20})</a>$|i', $email, $match)) {
  // not a valid email address
}

echo "Email Address: $match[1]<br />\n";
echo "Text: $match[2]<br />\n";
?>
[/code]

note: escaping the closing ">" of the opening a tag is not necessary, but i've got to have it there to keep the highlighter from borking.

in your original, the error may simply be that you're not escaping your quotes, so the engine is jumping out of your pattern before you're intending it to do so.
