A couple warnings from the developer:

• It's possible that you might see a drop in accuracy as your corpus gets trained up on the new anti-spam features. This drop in accuracy will be corrected once you've retrained POPFile a little.
• I'm suggesting that if you have a corpus with GREATER THAN 30,000 unique words (you can figure this out from the Buckets page) please wait for v0.21.1.

I have written about POPFile on Mac OS X in the past, and if you are interested in POPFile, you should read my previous articles:

• POPFile Installed on OS X
• POPFile Update in OS X

Upgrading POPFile

This assumes you have POPFile 0.20.0 or 0.20.1 installed in Mac OS X (10.3 recommended). If you have not installed POPFile in the past, please read the two above links. For example I am not discussing creating the StartupItem for POPFile here. You can find that information in the above links.

Just a reminder: you need the Developer Tools installed to compile the perl modules.

A) Download SQLite, DBI, DBD::SQLite, Digest::Base, Digest::MD5, and HTML::Tagset from the links provided above. Mount the SQLite disk image.

B) Open Terminal and type this: sudo cp /Volumes/SQLite-2.8.13/sqlite /sbin/ (type admin password)

C) Next you will be installing all the perl modules. These are all installed in the same manner. Remember that if you drag a folder from the finder to Terminal, it will write the path for you. So just type cd [space] and then drag the name of the folder (eg. DBD-SQLite-0.31) into the Terminal.

Installing the module goes like this:

In the Terminal, cd to the unpacked perl module's folder
perl Makefile.PL [return]
make [return]
make test [return]
make install [return]

Now you need to install the new version of POPFile.

1) Shutdown POPFile, go to http://localhost:8080/ (or the port number you changed POPFile to) and click “Shutdown POPFile”

2) Backup your current POPFile install. This is at /Library/POPFile

3) Keep the folder /Library/POPFile/corpus handy, you will need to move this to the new version of POPFile. Also keep “popfile.cfg” which holds your settings.

4) Download the new version of POPFile, in this case, popfile-0.21.0.zip

5) Replace the /Library/POPFile folder with the newly downloaded version of POPFile.

6) Be sure to move the corpus folder over to /Library/POPFile and the popfile.cfg file, or you will have no buckets, magnets, or anything for that matter!
