Just a few tests and man pages consults and it worked. In evolution just set a filter with "pipe message to a shell command" ang set "/usr/bin/bogofilter" and select to move to the SPAM folder.
Two things more:
1. Remember to set the filter high (up, up) to be the first filter applied to the messages (both on sylpheed-claws and evo)
2. Could it be good if the bogolearn script remove de messages after pass them to bogofilter? Or should it have a learn session only when some false positive or span confuses bogo?
