Some customers prefer using Matt Wright's popular "FormMail.pl" script.
Matt's older versions can be misused for spamming from anyone not
even having an account on the same server. However, if you still want to use it,
please download this new *save* version of FormMail.pl (v 3.12 from March 2004).
All you have to do before uploading is to customise the lines marked
in red.
