I used this procedure once on a web site - It is rather simple, but
worked quite well at the time:
Stop SpamBots from Harvesting email addresses
Using Character Codes in Emil Addresses
If you replace at least one alphabetic character on each side of the
"@" symbol in all of the e-mail addresses that you list at your site,
spambots probably won't be bothered to harvest them and you will
notice a huge decrease in the amount of spam that you get.
Browsers automatically convert these codes into their corresponding
alphabetic characters, so your "mailto:"; links will still function
properly.
e.g.: Replace the letters "a" in mailto:[EMAIL PROTECTED]
so it becomes: mailto:dla[EMAIL PROTECTED]ame.com
Here are the character codes that you'll need:
a a b b c c d d e e f f
g g h h i i j j k k l l
m m n n o o p p q q r r
s s t t u u v v w w x x
y y z z
You could probably come up with a script to convert ALL the
letters in the email addy.

From PHP Phrasebook by Wenz (Highly recommend for only $15):
<?php
function protectMail($s) {
$result = '';
$s = 'mailto:' . $s;
for ($i = 0; $i < strlen($s); $i++) {
$result .= '&#' . ord(substr($s, $i, 1)) . ';';
}
return $result;
}
echo '<a href="' .
protectMail('[EMAIL PROTECTED]') .
'">Send mail</a>';
?>
