Prevent Nail from attaching my message as a .bin file?

Question

When I pipe a very long change log into nail, I receive a blank email with a .bin attachment named ATT00001..bin in Outlook. The file is 36KB and contains the expected text but double spaced (presumably something to do with line endings). If the messages are brief, this doesn't happen.

How do I prevent Nail from converting my message to an attachment?

User-Agent: nail 11.25 7/29/05
MIME-Version: 1.0
Content-Type: application/octet-stream
Content-Transfer-Encoding: quoted-printable

I have had this same problem with the son of nail (heirloom mailx) on a Redhat ES 6.1. The problem in the end boiled down to the file not being an ascii, unix standard file (that is LF-only).

I solved this problem by removing the \r characters from the file before sending the mail.

cat logfile | sed 's/\r//' > logfile.new
