A script that will auto respond to a form ~ is there such a thing (free)

OK here we go. I have a form with about 30 - 40 check boxes, each indicating a particular word or PDF file that the user can request to download. I currently reply to these manually by attaching each requested file to a separate e-mail. Things are starting to hot up and I am now spending too much time replying. Is there a script available that would be able to reply automatically for me using a ready-made template for each file or something like that. Obviously I would probably have to re-write the form and upload all the articles to my web host, which is no problem. I have been searching various script sites but can't find anything like this. My web host uses Perl on an NT server and I currently use FormMail to forward the form to me by email.

Any help or suggestions would be great. Thanks.

Hi Jeepers, have you seen this one:

Thanks, I'll have a look at that. About ten mins after posting I found MailFile2 by the same person who wrote FormMail which also looks as if it might do the job as well.
