Python's smtplib sendmail is inserting line feed

Question

I am using smtplib sendmail and \n (line feed) is being added where there was just \r (carriage return).

This corrupts the file for use with the UNIX tnef utility. How can I keep the line feed from being added?

Thanks

Email servers are free to change line endings IIRC. They could be various platforms.

If you are transmitting an attachment, use a suitable encoding such as Base64.
