What is it?
PrePflog tries to solve the issue of double counting of email statistics in Awstats or Pflogsumm.
The double counting occurs when Postfix is used with an after queue content filter like Amavisd-new. The email passes through postfix twice, once before handing off to the filter and then when the email is received back from the filter for final delivery or forwarding. Each passage through Postfix generates email log entries.
It is a known issue that in this case Pflogsumm produced email statistics which were multiplied by two. No easy way of solving this in Pflogsumm is available.
