Apple mail has also been known to make an encoding error on text and csv attachments outbound. In essence it replaces line terminators with soft line breaks on each line, which look like =0D in the encoding. If the attachment is emailed to Outlook, Outlook sees the soft line breaks, removes the = then appends real line breaks i.e. 0D0A so you get 0D0D0A (cr cr lf) at the end of each line. The encoding should be =0D= if it is a mac format file (or any other flavour of unix) or =0D0A= if it is a windows format file.

If you are emailing out from apple mail (in at least mavericks or yosemite), making the attachment not a text or csv file is an acceptable workaround e.g. compress it.

The bug also exists if you are running a windows VM under parallels and email a txt file from there using apple mail. It is the email encoding. Form previous comments here, it looks like netscape had the same issue.
