====== Exim4 Tricks ======

Spam logging for analysis, and probably more in the future.

===== Logging spam mail at SMTP DATA ACL time =====

==== Exim Config ====

The log message includes the list of envelope recipients for the message. That means it also includes BCC-recipients, which might pose privacy problems.

    warn    spam        = nobody
            add_header  = X-Spam-Status: spam\n\
                          X-Spam-Score: $spam_score
            # ...
            log_message = Spam received: score=$spam_score; sender=$sender_address; recipients=$recipients

==== Log parse example ====

  grep 'Warning: Spam received:' /var/log/exim4/mainlog | sed 's/^.* score=\(.*\); sender=\(.*\); recipients=\(.*\)$/\1\t\2\t\3/'
