Integration with webmail app

[Chris Fortune]

Unusual configuration.  I want to use bogofilter with a custom webmail
application written in perl/MySQL.  There are no ~ Home directories but I
need to assign individual goodlist/spamlist/wordlist files for each user.
Also, emails are kept in SQL tables, so must be fed to STDIN via perl pipe,
I guess.  Does anyone have any suggestions, resources, scripts, faq's, et
cetera?  Thanks.
