296529 Anti-Spam Protection

Need anti-spam solution with a features similar to [login to view URL] or ChoiceMail One ([login to view URL]) for a SINGLE user. The script should run on the Linux server checking incoming mail. Messages should be verified against blacklist and whitelist. Pending messages should be deleted after N days. Confirmation messages "From:" field should have the email address where original message was sent to. I want to be able to access the mailbox using POP3 mail client. Clear installation instructions for the average Linux user... System requirements. If the script requires something "special" on the server, please let me know before starting the work. Control panel should include: - management of whitelist and blacklist (add/edit/delete email addresses) - listing and management of pending emails. If I manually select messages to accept, they should be automatically delivered to my inbox and address added to the whitelist - confirmation message editing Maybe I forgot something... Please check the mentioned sites for more features. I need this quickly. A working beta version in 7 days after the bid is accepted. Please post your bids only if you can deliver it or already have a solution. Thank you
