Sendmail Confirmation System is a plugin that reduces spam emails by filtering them through Sendmail milter.
In addition to its impressive spam-filtering capabilities, the Sendmail Confirmation System also comes with a range of useful features designed to help protect mail recipients from dangerous message attachments and HTML includes. This makes it a comprehensive solution that goes beyond just filtering spam messages.
One great benefit of using the Sendmail Confirmation System is that it is a milter plugin, which means that it can stop junk mail messages from being received in the first place. To do this, the software uses three unique algorithms. One of these is the "Check relay by NS" which simulates a dynamic whitelist and will always accept messages from mail systems that meet certain criteria. Another algorithm is the "check delays" algorithm, which uses statistical delivery delays to exclude direct mail not passed through a standard mail server.
Users should note that using this feature may mean that the delivery of mail from unknown but legitimate senders is delayed for up to 5 minutes. The third algorithm is the "autoconfirmation" algorithm, which authenticates senders of a mail contact through a filters statistics module. Messages from such authenticated senders are never delayed by the "check delay" algorithm.
Overall, the Sendmail Confirmation System is a reliable and effective software solution for reducing the amount of spam and junk emails received. Its security features go beyond just spam filtering, making it a comprehensive solution for protecting email recipients from dangerous messages. The latest update includes checks to prevent overwriting configuration data during installation as well as minor bug fixes in the ns-relay code.
