How to Install Pyzor on CentOS Web Panel for Postfix/Dovecot ?

Pyzor is a collaborative, networked system to detect and block spam using digests of messages.Using Pyzor client a short digest is generated that is likely to uniquely identify the email message. This digest is thensent to a Pyzor server to:

• Check the number of times it has been reported as spam or whitelisted as not-spam
• Report the message as spam
• Whitelist the message as not-spam

Since the entire system is released under the GPL, people are free to host their own independent servers. There is,however, a well-maintained and actively used public server available (courtesy of SpamExperts) at:

public.pyzor.org:24441

Open the following port in your firewall:
UDP 24441 Outgoing : Pyzor
TCP 24441 Incoming : Pyzor
