Actually it's mostly rewritten to only use the WP API and it had a (much needed) facelift :). It requires WordPress version 2.1 and above and will use all installed anti-spam plugins to filter the emails before sending.

Version 0.8 is available (requires WP 2.2 or 2.3).
= New in this version =
* Contact messages and replies are stored in the database.
* Anti-spambot question/answer field option.
* Can use Akismed and Bad Behaviour (if installed).
* Can send emails to multiple users (selectable from the options page).
* The form does not interfere with any plugins that modify or use the comments.
* Replies can be sent directly from the "Contact Messages" page.
* Many other improvements and fixes.
