I would like to ask you about any censorship / moderation system. Basic workflow of events:

1. Customer sends email to [email protected] from [email protected]
2. ACME administrator receives notification and can moderate email
3. After moderation administrator confirm an email and send it to [email protected]
4. John answears to [email protected]
5. Before the email is send it is moderated again by ACME administrator

What is important, that this functionality is easy to do with some CMS/CMF systems. The problem is that we do not want to use an extra domain and force customer to login an extra system. Customer should only use his own email box or desktop email application.

Thank you, Tomek
