Automated email form (in Perl) submissions

[Helen McMullan]

I have a form on my website that has somehow been taken over by some automated submission. I get 8-10 bogus forms each day.
The Perl program is part of my hosting service, but they do not support any verification process, etc.
I am an old COBOL programmer; taught myself HTML and CSS, but not very savvy with Perl or even the terminology related to this kind of issue. My hosting tech support said they do not do "email validation" in the script offered. So I "Googled" "email validation perl" and most of what came back appeared to be code to ensure the submission was from a valid email address.
I don't think that is my problem--the email address may or may not be valid--perhaps it is valid. What I know for sure is that the information in the submitted form is not valid.
Can you tell me what I need and how/where to get it?
Thanks for all,
Helen

Adding a question to from like "2+2=" and later checking for 4 in program will protect your from most bots.

P.S. Consider reading "Learning Perl" (no earlier than 4th edition) or "Beginning Perl" - they both have good exercises.
