Hello, I'd like to test different Postfix configs and approaches for spam fighting but I need to have a way to evaluate the effect of different rules and configs, without affecting normal service. I find "warn_if_reject" option very useful, so I could make some kind of stats based on warnings being logged.
But now I'd like to go one step ahead, taking a different approach: marking the mail message (adding a custom-defined header, e.g) in case it were going to be rejected. So I could receive all my email "without disruption" and classify the emails using client-side filtering, and then dropping "supposed-to-be-rejected" mails to a different folder. The advantage is that I get the whole body of suspected emails, instead of a simple warning in server's logs, so it's simple for me to manually (yes!!) review mail being caught and look for false positives. Is there any easy way to get this done? Do you know any other postfix feature similar to "warn-if-reject" which could help me? TIA. Cheers, -r
