We get some of emails with attachments included in body as uuencoded files. It's very old format but unfortunately it is still used.

Haraka should process such emails, extract uuencoded files from them (cut from body) and provide them as attachments.

It looks like this library is capable of doing all the work: https://www.npmjs.com/package/uue

For example, you can use this email

MIME-Version: 1.0
Received: by 10.217.58.201 with HTTP; Tue, 6 May 2014 05:57:27 -0700 (PDT)

We have the same issue. Attachment content of such emails goes to body.

Today I looked at the state of uudecoding plugins on NPM and was...unimpressed. Nothing there I'd sign up to maintain. This is unlikely to ever be supported within Haraka but a motivated person could implement it as a plugin.
