As an extension to the JangoMail Spam Blocker, every day starting wtih today, IP addresses that send mail.jangomail.com (the incoming e-mail handler for @jangomail.com e-mail addresses) the highest amount of spam e-mail will be added to a blocklist that will prevent them from establishing a connection on port 25 to mail.jangomail.com.
This additional security measure will further reduce the amount of spam received as replies to mass e-mailings, and will conserve overall JangoMail network resources and bandwidth.
