Description

DO NOT USE - security issue and Acquia will no longer support or maintain it.

Spam filtering SaaS from Acquia. Free for up to 50 "ham" messages a day.  Scans message then provides a captcha if appropriate, scores each message for reputation, spam etc.  I never tried this module and anecdotally I've seen mixed reports / people suggesting it's not all that good.
