Good Pattern for a response form

I would like to do a response form on one of my sites instead of posting
an e-mail address for spammers. I've taken a couple of examples from
sites, but the code looks clunky and non-conformant to my inexperienced eye.

Also, on the sites I've found you can get the e-mail address simply by
viewing the page source. It seems to me there should be a way to hide
that, but as I say I'm hardly an expert.

Can anyone recommend a good site to use as a pattern? Needless to say,
I'd like it to be as easy to maintain and standards compliant as possible.

Look at the NMS replacements for Matt Wright's forms. They allow you to
specify an alias for the recipient in the form, and the script uses that
alias to work out which address to post to (you configure a table of
aliases and addresses in the script).

That rather depends on what you want on the form. Such as answering
questions, writing messages, etc. But what sort maintenence do you need
on a form once you've written it?

A valid, and logical way, of structuring parts of forms is to use the
proper form elements, as set out in the specifications, perhaps with a
few extra formatting elements and CSS to neaten things up, and avoiding
using tables. For example:

<form action="/cgi-bin/FormMail.pl" method="post" accept-charset="us-ascii, iso-8859-1">

<fieldset>
<legend>Why did you visit this site?</legend>

<div class="multiplechoice">
<label><input type="checkbox" name="visit_reason" value="Boredom"> I needed more excitement in my life</label><br>
<label><input type="checkbox" name="visit_reason" value="Broken PC"> Trying to fix my PC</label>
</div>
</fieldset>

<fieldset>
<legend>Did the site work properly?</legend>

<div class="multiplechoice">
<label><input type="radio" name="site_okay" value="Yes"> Yes</label><br>
<label><input type="radio" name="site_okay" value="No"> No</label><br>
<label><input type="radio" name="site_okay" value="Don't know"> Don't know</label><br>
<label><input type="radio" name="site_okay" value="No answer" selected> No comment</label>
</div>
</fieldset>

<fieldset>
<legend>Your details</legend>

<div>
<label for="name">Name:</label><br>
<input type="text" name="realname" id="name" size="50" maxlength="70">
</div>

<div>
<label for="address">E-mail address:</label><br>
<input type="text" name="email" id="address" size="50" maxlength="70">
</div>
</fieldset>

<fieldset>
<legend>Message details</legend>

<div>
<label for="subject">Subject:</label><br>
<input type="text" name="subject" id="subject" size="50" maxlength="70" value="survey form response">
</div>

<div>
<label for="message">Message:</label><br>
<textarea name="message" id="message" cols="50" rows="20"></textarea>
</div>
</fieldset>

<fieldset>
<legend>Action</legend>

<div>
<input name="recipient" value="webmaster" type="hidden">
<input type="hidden" name="redirect" value="/response.html">
<input type="submit" value="Send"> your comments.
</div>
</fieldset>

</form>

Notes:
-----
1. My "multiplechoice" CSS class was there to play with margins/fonts.
2. I've deliberately made the message area big enough to write a message
without it being a pain.

A very simple method, that I am sure will be worked around by the spam
harvesters, is to replace the characters in the email address with their
letter codes. for example, rather than carolyn (AT) marenger (DOT) com, use:
%63%61%72%6F%6C%79%6E%40%6D%61%72%65%6E%67%65%72%2 E%63%6F%6D. This
displays and if used in a link works fine, but in theory makes it just a
little harder for a harvesting script to find.

In my case, I use spam assassin, and even with my email address posted I
am only receiving 1 or 2 spam messages in any given week.

Don't waste time concentrating on the wrong issue.

Any response script which permits an arbitrary email address to be
specified from a form submission as a destination is functionally a
spamming gateway, and will get your site blacklisted in due course.

If you have a limited menu of contact addresses on the server side,
then they can be specified by a nickname from the script, without
revealing the true email address. Read the notes that come with the
NMS re-engineered formmail script. Although you'll find that many
hosters will refuse to host anything whose name resembles "formmail"
(the spammers are permanently scanning for them).

Well, I'm assistant postmaster, so anyone who spams me is assured of
being blocked from the whole department (in fact I just reported one
to the central postmaster, so that'll be blocked from the whole
campus).

But you can rename the script...

Just a routine remark at this point that this sub-thread is way off
topic for the stylesheets group, so the lurkers should not go off
thinking they've heard everything they need to know about the topic.
This is serious stuff, and can get you blacklisted if you don't know
what you're doing, so please go and get advice in an appropriate
place if you're planning to do this.

Meantime, back to Tim:

You might keep your service provider quiet for a while, if you called
it something different from the names that are routinely searched for.
But if the script isn't properly designed and set up (see above), it
still might act as an open mail proxy, and a determined spammer might
find it and (ab)use it. Any contact form is potentially at risk.
Make it bulletproof: "security by obscurity" only goes so far (which
isn't far enough!).

I was thinking of the situation of using a better script, like the NMS one
used in a sensible manner, and renaming it to avoid the ire of idiot hosts
who just want to outlaw something called formail regardless of what it
actually was.

Interestingly, as I use the NMS script in that manner myself, I notice my
web logs show attempts to find other well-known bad scripts from time to
time, but they don't look for that one.

That's what I thought - I just wanted to spell it out...

No surprises there. I guess every publicly-accessible web server's
log has examples. I know all of ours log them. I think this is even
one of nessus standard tests, isn't it?[1] (Don't try this at home,
kids: running nessus against someone else's server would be a criminal
offence in many jurisdictions.)

but they don't look for that one.

As long as there are easy pickings elsewhere, they don't need to.
But if the script /was/ insecure (I accept that in your case it
isn't), then it only takes one spammer to find it. For example by
spotting the contact form which invokes it.

I use a simple javascript routine to write the address in DHTML - so far

my mother's email has been on the web over a year - and she gets no
spam! (She does not post to newsgroups!)
Its nothing fancy - just stick this where the mailto: used to go (change
the
user and place fields as required).

<script language="JavaScript" type="text/javascript">
<!-- //blocks indexing by harvesters
user = "user";
place = "mydomain.co.uk";
document.write('<a href=\"mailto:' + user + '@' + place + '\">');
document.write(user + '@' + place + '<\/a>');
// -->
</script>
