If it's machine-generated spam, you could try a honeypot. Add this to the
form:
"<div id='challenge'>To confirm you are not a real person, tick the
box: ".
"<input type='checkbox' name='confirm' value='yes' /><br /></div>"
You also need to set
$HTMLStylesFmt['challenge'] = "
#challenge { display: none; }
";
Then in the code that processes the form to send the email, add this:
if (@$_POST['confirm']) Redirect($pagename);
The theory is that a machine will fill in any fields it finds in the code,
because it can't tell that the confirm field is invisible. A more or less
intelligent life form, such as a human, will unwittingly leave the field
empty, thereby avoiding the Redirect.
There is anecdotal evidence that this technique is effective in some
cases. YMMV
