Is there any opensource email verification script?

[yoki]

Hi,

I'm looking for an opensource script that lets a user subscribe to a mailing list. Once the user submits his email, he gets an e-mail with a link that confirms that he registered for this mailing service. Can someone refer me to a good one? 🙂

Thank you!

Well, I haven't looked, but you might try searching around on HotScripts .
