    3 things you can try.

    Create a graphics file of your email address. The bots can't read it
    (yet), but people can. Not that great if you have a long complicted
    email address that peopel have to type in.

    Create a web form that people can use to send you a message instead of
    using email directly. Requires a web host that allows CGI scripts and of
    course a CGI script. Try [url]http://www.scriptarchive.com[/url] and
    [url]http://cgi.resourceindex.com[/url]

    Encode the address using Javascript which the bots can't read but people
    can click on. The user has to have Javascript turned on in their browser
    for this to work. There's a free program here to do it for you:
    [url]http://www.railheaddesign.com/pages/software/spamstopper/spamstopper.html[/url]

    There's more information on stopping spam here:
    [url]http://www.macintouch.com/spam.html[/url]

    Unfortunately I can't tell you how well it works because I haven't had a
    chance to implement the above ideas yet.

    Some of the older ones are such as Matts Scripts.

    There are other places that have written new ones or updated the
    'Matts' ones to overcome that.

    What you need is a "referrer" statement in the script so that the form
    mail can only be sent from the web form (via its own domain). That
    prevents spammers from hijacking the script itself remotely.

    Another possibility is to have the form mail address hard coded into
    the form mail CGI. That way its not in the page source code that a
    spam bot could locate.

    A referrer can easily be faked.

    This is the only way to really protect a form.

    Sorry, not sure what has happened to the file. Here is the script:

    Well, there's a script called "formmail.pl" that, if badly configured
    (you have to go out of your way to make it insecure) can be exploited
    in much the same way as an open email relay - so you'll see spam from
    a formmail script occasionally.

    Matt of "Matt's script archives" is no longer updating his scripts,
    but a set of drop-in replacements has been made, by the folks participating
    in the sourceforge projects. You can find them at:
    [url]http://sourceforge.net/projects/nms-cgi/[/url]

    They're well-doented and much more secure than the scripts that they
    replace. There might even be something in there specifically for
    munging a mailto: link, I haven't looked through it in a while.

    I've read several suggestions here in this thread; I'm not sure there _is_
    a best. Use the one that suits both your talents and your needs. :-> I've
    stopped putting my email address on my Web pages and use a form
    instead. I'm sorry that I can't suggest that particular form, as my ISP
    built it and requires it's use for their own security. I'm very happy to
    have them on the hook. It hard codes the recipient and stores it in a
    location not accessible via browsing.

    In addition to the other suggestions, here's one I've seen but never tried:
    choco<small></small>flakes.com

    The disadvantage is that it's not clickable, but it's human readable when
    in HTML and not machine readable in the source. The nice thing about a form
    is that people don't have to copy and paste your email address into their
    email program. I'm not sure how the version above copies, but I'm guessing
    it's fine.

    Now your email address should be safe from SpamBots (computer programs
    that crawl the net looking for email addresses). Most SpamBots look for
    the give-away 'mailto:blahblah.com' link, and more complicated ones
    look for '' symbols. With this script in your page, there's not a
    single 'mailto' or ''. As far as the bots are concerned, it's just a
    bunch of meaningless numbers. This should help keep your email address
    off of future bulk email lists.

    I use a bit of JavaScript to construct the address dynamically. The
    bots don't execute JavaScript code, so they don't get an address.
    The downside is that visitors must have JavaScript enabled in order
    to see it. But it works.

    Here's the script. You'll obviously want to customize it for your
    e-mail address (replace "mymailbox", "mydomain" and '.test' with
    appropriate strings.)

    <script language="JavaScript">
    <!--
    function insertmaillink(addr, linktext)
    {
    var linktarget='mailto:'+addr;
    doent.write('<A HREF="'+linktarget+'">'+linktext+'</A>');
    }

    function insertmaillinktext(linktext)
    {
    var myname="mymailbox"; var mydom="mydomain";
    var myaddr=myname+''+mydom+'.test';
    insertmaillink(myaddr, linktext);
    }

    function insertmaillinknotext()
    {
    var myname="mymailbox"; var mydom="mydomain";
    var myaddr=myname+''+mydom+'.test';
    insertmaillink(myaddr, myaddr);
    }
    //-->
    </script>

    Now you use insertmaillinktext() or insertmaillinknotext() where you
    need a mailto: link.

    Instead of:

    <A HREF="mailto:mymailboxmydomain.test">
    [email]mymailboxmydomain.test[/email]
    </A>

    use:

    <script>
    <!--
    insertmaillinknotext();
    //-->
    </script>

    And instead of:

    <A HREF="mailto:mymailboxmydomain.test">
    Click here to mail me
    </A>

    use:

    <script>
    <!--
    insertmaillinktext('Click here to mail me');
    //-->
    </script>

    This has worked very well for me.

    Nobody has yet mentioned the method that imposes the lowest requirement
    on your legitimate readers. You can encode the email address (or even
    the whole href attribute) using numerical ASCII codes:

    <a href="mailto:&#99;&#104;&#111;&#99;&#111;&#64;&#10 2;&#108;&#97;
    &#107;&#101;&#115;&#46;&#99;&#111;&#109;">ChocoFla kes</a>

    or

    <a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#99 ;&#104;&#111;
    &#99;&#111;&#64;&#102;&#108;&#97;&#107;&#101;&#115 ;&#46;&#99;&#111;
    &#109;">ChocoFlakes</a>

    Even very old browsers (and new browsers with JavaScript disabled, etc.)
    will have no trouble with this, but it seems that spammers don't bother.
