I stand and must make a "mail a friend" feature. The only requirement I have received is that it should be as close to spam-free as possible.
My framework is that I have jsp available (of course, with underlying web and app server - but it is not necessary to carry out the task?).
I've looked a bit online and found CFFormProtect (http://cfformprotect.riaforge.org), which unfortunately makes use of Cold Fusion. I would rather stick to jsp, where possible. Someone who is familiar with a similar extension? Whether it is open source or cost money is no problem (in other words, in real borders ).
I've also looked a bit on captcha. It seems I will give a bad user experience, so I would prefer to avoid. Charging the user to enter his own mail and then confirm it is also a possibility, but also one I would rather avoid.
All ideas and the like is more than welcome.
