If you can pare it down to just the mime-encoded part (assuming it hasn't
been trashed by the attachment process) and put that in a file by itself,
a solution that was posted years ago was:
perl -MMIME::Base64 -ne 'print decode_base64($_)' < your_file
This should print it to the console, and I assume you'd add a '> new_file'
on the end to dump the output to a file.
But that won't handle this if it's an ongoing problem. I assume that,
whereas the MUA is supposed to follow certain rules in encoding and
inlining attachments, Microsoft, predictably, doesn't do it right, and
consequently bungs things up. I don't have a solution for brain dead mail
clients from monopolistic behemoths. I wonder if, instead of including an
existing email as an attachment, whether the sender can simply *forward*
the original mail. It *sounds* like they're *attaching* an email to an
email, which may not properly preserve encodings and attachment boundaries
in the original email.
