Training using Exim4.6 and Maildir problem

[Pieter Claassen]

I would like to train bogofilter but have the following problems/fears:

1. bogominitrain doesn't seem to take Maildir format as input? Is there a way 
to make it look at Maildir folders?

2. If I cron the following job

bogofilter -d /etc/bogofilter -B ~/Maildir/cur -n
bogofilter -d /etc/bogofilter -B ~/Maildir/.Suspect/cur -s

Then I fear I will be retraining on the whole spam/ham email lists which will 
skew the scoring and break the system in the long run. How do I only train on 
the new messages added to the .Suspect and my ham folders?

I read my mail via imap and therefore don't have the option to use my MUA to 
run bogofilter over incorrectly classified mails.

Lastly, I might be a bit daft, but the documentation doesn't seem to indicate 
clearly when it is ok and when not to train/retrain over an existing list of 
emails.

Thanks,
