That's not a problem: Bayes will wind up ignoring any Exchange-specific headers that occur in all mails. > so, what you're saying is something like "unless you change your mail > client, you can't feed spams to SA", is that it? > Yeah. But create two public folders, SPAM and NOT-SPAM. Hit it via IMAP from say, Outlook Express, and use MailNavigator to convert the OE DBX files to MBOX format on the spamassassin gateway, then sa-learn them. Or even more efficient, do it from Mutt or another IMAP client right on the spamassassin gateway. If the users drag & drop the mails into the public folders, the headers should remain intact. This works extremely well. -tom
