* Question: What is transferred from my server to the central server as part of the spam report that is used to build the DNS Blacklist?

All IP and URL/URI checks are performed a simple DNS lookups through SpamAssassin and the sending IP address or domain is used for this lookup just as any other DNS blacklist (Spamhaus, etc.).

** Answer: The qpsmtpd plugin captures the sender domain and the sending ipaddress, the qpsmtpd plugin which rejected the mail and the plugins return text.

 

When your own server, based on your configured DNS blacklists, rejects a mail the SMEOptimizer qpsmtpd plugin will capture the sending IP address and the sender domain as well as the return text from the dnsbl plugin (Usually a link provided by the DNS blacklist service for further details). These details are stored in a local MySQL database and on a hourly basis transferred via HTTPS PUT to the SMEOptimizer server. Here, based on a score system, they are added to the shared DNS Blacklist for all to benefit from.
