The SpamBayes team is pleased to announce release 1.0.4 of SpamBayes.
This is a bug-fix release that fixes one major issue with the 1.0.3 release: if a 1.0.3 sb_server user's mail client tries to connect to the mail server, and the DNS lookup succeeds but the connection fails, then sb_server will write warnings to the log until there is no disk space left to do so.
This specific problem is fixed in 1.0.4, and in addition 1.0.4 is again built with Python 2.3 (not 2.4), so should more closely match 1.0.1. Connection errors are also now only logged once per hour (unless the verbose option is set). No other changes have been made.
As such, we strongly recommend that all sb_server users upgrade. sb_imapfilter, Outlook plug-in, and other users should notice no difference between 1.0.3 and 1.0.4 and do not need to upgrade.
You can get the release via the 'Download' page at
Enjoy the new release and your spam-free mailbox :-)
As always, thanks to everyone involved in this release. (For the curious, the oft-delayed 1.1a1 release should be made next week.)

--- What is SpamBayes? ---
The SpamBayes project is working on developing a Bayesian (of sorts) anti-spam filter (in Python), initially based on the work of Paul Graham, but since modified with ideas from Robinson, Peters, et al.
The project includes a number of different applications, all using the same core code, ranging from a plug-in for Microsoft Outlook, to a POP3 proxy, to various command-line tools.
The Windows installation program will install either the Outlook add-in (for Microsoft Outlook users), or the SpamBayes server program (for all other POP3 mail client users, including Microsoft Outlook Express). All Windows users (including existing users of the Outlook add-in) are encouraged to use the installation program.
If you wish to use the source-code version, you will also need to install Python - see README.txt in the source tree for more information.
