Yes, should be fine. The sa-learn will ignore X-Spam-* header fields. The presence of Delivered-To, X-Envelope-To, X-Envelope-To-Blocked and X-Quarantine-ID fields shouldn't be a problem, even though bayes may store these as tags. > 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? Yes. Some older versions of sa-learn needed an option --dir when given a directory as an argument. Mark
