Pflogsumm is a log analyzer/summarizer for the Postfix MTA. It is
designed to provide an over-view of Postfix activity, with just enough
detail to give the administrator a "heads up" for potential trouble
spots.
Pflogsumm generates summaries and, in some cases, detailed reports of
mail server traffic volumes, rejected and bounced email, and server
warnings, errors and panics.
