Spam Control Recommendations for ISP’s

I have information for ISP’s to stop spam
Other recommendations, ISPs should:
· Open relays should be reconfigured as secure relays. ISPs should test all remote mail servers that connect to that ISP to ensure that they are not configured as open relays or subscribe to third party open relay lists available from many antispam organizations.
· Regularly scan for misconfigured or outdated programs that can be used to create e-mail.
· Ensure an off-the-shelf proxy should be configured to only allow users on the internal network to use the proxy. ISPs should test their customer's proxies to determine if any are misconfigured and could allow for third party abuse.
· Develop methods for discovering compromised computers and quarantine those that show signs of infection.
· Implement authenticated e-mail solutions that require valid credentials from users before they can send mail, usually a username and password.
· Develop and implement methods for blocking the automated generation of accounts. For example, verify that a registration request isn't being generated by an automated script.
· Secure all Web-based redirectors that could be used by third parties without permission.
· Develop a system for customers and external parties to report spam. The system should be simple to use and keep the content of the original e-mail intact so that it can be used to improve filtering and potentially trace spammers for litigation purposes.
