I completely understand what you say. But please understand I already considered those "issues" and that my decision to use a such system was thinked before. The antispam feature of Imail is unsecure, and my customers urge me to provide them a spam challenge system. I will use myself that system like every satisfied customers that use that system. > We track the ratio between legit and useless messages for > over two years now.

We have thousand users. I have some mailboxes that are filled with 300+ spams everyday (it's a reality). This is becoming completely unusable. Filters just work...
