Module provide protection against all spam-bots without JS processing
E-mail No-Reply
Are you looking for a way to specify a no-reply email address for all mail coming from your Drupal site without having to muck around with the MTA configuration on your server? You might think, "Oh, I'll just go change the site email address in Drupal." Unfortunately, Drupal sends important notices such as user registration to that email address, so if you change it to a noreply address, you will no longer receive those notices. By default, many contributed modules such as Backup & Migrate and Mollom use this address as well. Additionally, anywhere the [site:mail] token is used, that noreply address will show, which is probably not what you intended.
What you really want is the from field in the email to use the noreply address, right? This module is an extremely simple module that adds a new field to specify a separate no-reply email address for all outgoing mail. Any email that goes out that from your Drupal site will be from this noreply address, but you will still receive your important emails at your site e-mail address.
Regcheck
Regcheck is a super lightweight and simple module that adds a hidden checkbox on the user registration form, and kills the registration process if it is checked. This is an easy way of keeping registration open on your site while still being protected from robot users.
Just download and enable the module to utilize its functionality.
