INTRODUCTION v0.20.1 is a minor update on v0.20.0 to address the performance problems that some people were seeing with the introduction of the BerkeleyDB for storage of the corpus. v0.20.1 sets the BerkeleyDB cache size (i.e. the amount of the corpus that is kept in memory) to 64KB and it can be controlled through the bayes_db_cache_size parameter if needed. The default should work for everyone, you can set this to a higher value to keep more of the database in memory at the cost of using more memory. There are also a number of bug fixes in v0.20.1: 1. If you set a password and used X-POPFile-Link you were unable to get past the password screen when clicking on an XPL. (bug #831472) 2. In some instances when the connection between the POP3 proxy and the mail server was lost it was possible to get in a deadlock where POPFile was waiting for a command from the client and the client was waiting for a response from POPFile. (bug #829947) 3. It was not possible to add pseudowords (e.g. header:From) as ignored words, now it is. (bug #827785) 4. Magnets that included $ or @ could be incorrectly matched when the @ or $ was followed by __. (bug #826765) ESSENTIAL READING IF YOU ARE UPGRADING TO v0.20.1 1. BACK UP YOUR OLD INSTALLATION: POPFile makes this really easy, just copy the entire POPFile directory somewhere. You can then safely install POPFile v0.20.1 on top of your current installation; I just think a back up is a sensible precaution. 2. IF YOU ARE RUNNING WINDOWS: Please read the section below I AM RUNNING WINDOWS AND NEED TO CHECK MULTIPLE EMAIL ACCOUNTS SIMULTANEOUSLY 3. ON WINDOWS POPFILE IS NOW AN EXE. Windows users will now be able to see POPFile running in the Task Manager with an executable called popfileXX.exe where the XX is one of f, if, b, ib depending on configuration. POPFile is started by running popfile.exe which chooses the appropriate popfileXX.exe This might cause your firewall to ask about giving popfileXX.exe permissions, in addition if you had allowed Perl permissions in your firewall they are NO LONGER needed. 4. The installer will cause POPFile to run in the foreground if the database upgrade is required so that the upgrade process is evident to the user. Once upgraded you can switch to background my going to the Configuration tab and changing "Run POPFile in a console window?" to No. I AM RUNNING WINDOWS AND NEED TO CHECK MULTIPLE EMAIL ACCOUNTS SIMULTANEOUSLY Because the time taken to start a new process on Windows is long under Perl there is an optimization for Windows that is present by default: when a new connection is made between your email program and POPFile, POPFile handles it in the 'parent' process. This means that the connect happens fast and mail starts downloading very quickly, but is means that you can only downloaded messages from one server at a time (up to 6 other connections will be queued up and dealt with in the order they arrive) and the UI is unavaiable while downloading email. You can turn this behavior off (and get simultaneous UI/email access and as many email connections as you like) by going to the Configuration panel in the UI and making sure that "Allow concurrent POP3 connections:" is set to Yes, or by specifying -pop3_force_fork 1 on the command line. I AM USING THE CROSS PLATFORM VERSION POPFile requires a number of Perl modules that are available from CPAN. New in v0.20.x are the need for the following: BerkeleyDB Text::Kakasi (if you want Japanese language support) Encode (if you want Japanese language support) I LIKE TO LIVE DANGEROUSLY In a future version POPFile will add official support for message classification through the SMTP and NNTP (Usenet news) protocols. There are currently proxy modules for these protocols that work with v0.20.1, but they have not been fully tested. If you are interested in getting them get them here: http://cvs.sourceforge.net/viewcvs.py/*checkout*/popfile/engine/Proxy/SMTP.pm?rev=1.22 http://cvs.sourceforge.net/viewcvs.py/*checkout*/popfile/engine/Proxy/NNTP.pm?rev=1.21 and place them in POPFile's Proxy/ directory. DOWNLOADING You can obtain the latest releases of POPFile by visiting http://sourceforge.net/project/showfiles.php?group_id=63137 UPGRADING Just install POPFile on top of the currently installed version. But did you read the ESSENTIAL READING above first. INTERNATIONALIZATION This minor update includes localization into Turkish.
