MAIL LOG FILTER This is a small program which solves a big problem. That is, MLF processes your mail log and attempts to identify duplicate entries caused by using multiple MTAs (for anti-virus and -spam). Effectively, this filter is preventing log analyzers from counting the same email message twice. The default action is that both log entries of the same message are merged, therefore both sender and remote relay agent information are preserved. Please, proceed to the project pages for more information and download.
