site usage of bogofilter.

[David Relson]

Greetings,

The folllowing question has come up:  How can bogofilter's spam and ham 
word lists be kept high quality and up-to-date without overloading the 
sysadmin with the maintenance taks?

Suppose a bogofilter site had system level word lists _and_ user level word 
lists.  The system level lists would be provided (maintained?) by the 
sysadmin and would provide a basis for spam detection.  In addition, each 
user would have his/her own word lists (private) and be responsible for 
maintaining them.  (Of course, a user could choose to do no maintenance, in 
which case bogofilter would just use the system level lists).

The system level lists could be updated as often (or rarely) as the 
sysadmin wanted.

The user level lists need a simple way for the user to add messages to the 
spam and ham lists.  Suppose the system had two special email addresses, 
e.g. spam at example.com and ham at example.com.  The user could (would) forward 
received messsages to these special addresses.  The messages in the spam 
and ham mailboxes could be added to the appropriate user's word lists 
(determined by examining the forwarding info in the message header) by a 
procmail recipe, a cron job, or other mechanism.

Note:  The ideas above are mostly derived from postings on the bogofilter 
mailing list.  I'm not sure if I've added anything other than collecting 
them into a single message.  None the less, I think it's time to think 
about deployment and usage ideas and issues.
