The problem is caused by bad RPMs that write out text during install/update/etc
and that text happens to contain non printable ASCII characters (like a carriage
return character or some garbage like that). The mail program on linux sees
these characters and automatically converts the mail to base64 before sending
it.
The patch I have to fix it is to put a " /usr/bin/tr -cd '\11\12\40-\176' " to
filter the yum response before it is mailed. Works for me :
