I understand that. My question is whether the message file, as stored is 
amavis spam quarantine dir, is in a format suitable for use by sa-learn.

So, if I copy some messages (which I consider ham) from 
/var/blockedmail/spam/ to /path/to/ham/folder/ and I run:

    sa-learn --ham /path/to/ham/folder

will sa-learn understand these files correctly and process them without 
problems for training?

Thanks,
