RE: [vps-mail] Bayesian AND BlackLists

["Lang Zerner" <lang@xxxxxxxxxxxx>]

If your IMAP folder is stored as a single file, it's probably in mbox
format, so I think you probably need to use the --mbox switch with sa-learn:


sa-learn --spam --mbox /home/jimsmith/learnspam

sa-learn --ham --mbox /home/jimsmith/learnham

That tells sa-learn that the target file is a sequence of individual
messages stored as a single mbox file.
