My 0.02$CURRENCY - when fetchmail finds a mail such as this it should
create a new mail, addressed to the postmaster address, with the
illegal email as a text/plain attachment.

If you're feeling kind, insert a blank line before the offending
illegal header and include that altered version as a message/rfc822
attachment (but still have the text/plain attachment)

There's no point in passing on the known broken email as is, and
simply "fixing" it may result in more problems.  At least if the
postmaster gets it as an attachment then they can decide how to handle
it.

Personally, I'm curious to know what mail client is producing such
borken emails, and what MTAs are passing them on.
