Formmail generator - any good solution?

Dear friends,
 
Were looking for some formmail alternative for our customers. Would be nice some generator which Ive seen some panels install, I think HC does not have that, perhaps a suggestion.
 
We have ASPEMAIL, etc. but its a bit too hard for some users. We have Matt's Formmail.pl and it's nice, only thing is, under IIS7 + Perl for some reason we had problems of variables getting mixed up by PERL and result was form results getting mixed up... So we installed it under Linux, only this is we have to free up each domain that wants to use it in the Referers part, which is time consuming.
 
I saw another one which is really interesting, PHPformgenerator: http://phpformgen.sourceforge.net/phpform
 
Its nice, one can build a form easily via web. The problem is, it generates such forms so user can download them and poses a security risk, as anyone can use the generator and create forms to send spam.
 
Any ideas how to make it secure without requiring too much work?
 
Any other alternatives you guys have been using?
 
Thanks.
