One is to have learning folders (imap or webmail), the other is to forward as an attachment and have a script that extracts the original from the mime. A simple redirect may work well enough, but there are (at least) a couple of problems. Firstly sa-learn should ideally be able to find the trusted and internal networks to reproduce the same tokenization that it does on classification. It would be useful to strip any received headers that break this. Secondly, if you use autolearning then sa-learn must be able to identify if a mail has been previously learned,and this requires all additional received headers be stripped.
