The form handler in Frontpage won't fool anyone, since the email address is
still visible in the code (in the 'webbot' code).
eg:
<form method="POST" action="--WEBBOT-SELF--">
<!--webbot bot="SaveResults" S-Format="TEXT/CSV" S-Label-Fields="TRUE"
B-Reverse-Chronology="FALSE" S-Email-Format="TEXT/PRE"
[email protected] B-Email-Label-Fields="TRUE"
S-Builtin-Fields -->
<p><input type="text" name="T1" size="20"><input type="submit"
value="Submit" name="B1"><input type="reset" value="Reset" name="B2"></p>
</form>
See - the email address is in plain view and spam-bots can still harvest
this.
The issue you would be asking about is to place the "To" email in the script
that sends the email, rather than in the form, but you can't do this with
the default frontpage form handler; you need a third-party script suitable
for your server (unix/linux/windows), and depends on what your host supports
(they may even offer such a script as part of your hosting service)
