Ryan, I've found that if mail is sent directly to a mail-enabled Public Folder's email address, IE from amavisd-new or Postfix, its headers will make it through with IMAP. However, if an email is moved to or from a Public Folder with Outlook (regardless of whether or not the public folder is mail-enabled), then its headers get truncated. So I can at least train bayes by having any emails over my threshold of 6.0 get redirected to [EMAIL PROTECTED] by amavisd-new and they show up in the SPAM folder. And I can sa-learn them. Unfortunately that's about it though... Moving false positives to a Public HAM folder truncates headers, as does false negatives getting moved to the SPAM folder. I think bayes can still learn with incomplete headers, though it's not ideal. I'm not sure how bayes can be used with Exchange without bypassing Exchange completely in some way. I'd like to see other people's solutions to this problem (or maybe they just don't know about the problem). Maybe somebody can come up with IMAP client patch that can retrieve the full headers, as they are actually retained by Outlook when messages are moved to or from Public Folders, just not when IMAP is used.
