The standard 'pipe.pl' utility script shipped with POPFile does not update the message history when the message is classified. However only a few simple changes to the script will make it update the message history which means the UI can be used to reclassify the message and update the corpus.
The attached 'pipe-history.pl' script was created by modifying the 'pipe.pl' script from the forthcoming POPFile 1.1.2 release. This 'pipe-history.pl' script will also work with the POPFile 1.1.1 release.
The 'pipe.pl-pipe-history.pl-changes.diff' file gives details of the changes which were made to create the new script.
