Bayes auto learn

[James R. Stevens]

Does anyone have a script to extract the attachments and feed the rest
to sa-learn? I am using Outlook as an MUA.

...
Otherwise pretty much the only way to do bayes learning via forward
reliably for most mail clients is to set up a system where your users
forward the original email as an attachment. You can then write a little
script to extract the attachments and feed them to sa-learn.

To be honest with you, what you want to do is VERY difficult unless you
make a lot of assumptions about the MUA in use.

You're worried about fixing the headers... but what about the message
body? encoding formats? etc.

Even if you have a script that fixes the headers, Most email clients
completely re-encode the message body when you forward it, inserting
some things, removing others, and the resulting message bears little
resemblance to the original from a bayes perspective.

Some mail clients are good about this, but most are not.

If you've got a well behaved mailclient, you can use something like this
script that fixes headers to remove forwarding headers:

Otherwise pretty much the only way to do bayes learning via forward
reliably for most mail clients is to set up a system where your users
forward the original email as an attachment. You can then write a little
script to extract the attachments and feed them to sa-learn.

(I for one can vouch that even forwarding as attachment won't work with
Eudora.. Eudora discards vital parts of multipart/alternative messages
and they cannot be recovered, ever.)
