Fair enough.

A text file is produced with the email in it, the attachment is text/plain
and the attachment has CRLF for each of it's lines.

It seems the problem is with the MUA (mutt) and I believe that mutt gets
the mime type from libmagic which also reports text/plain for the DOS text
file. It can the tell the difference since "file dos.txt" gives

"ASCII text, with CRLF line terminators"

So I guess I can get it to give a different output for the mimetype too.

Thanks for all your help with this,

Scott.
