The OpenSSL S/MIME implementation doesn't follow the MIME
specification when writing out messages in that format. As a result,
messages created with this library will choke when passed through
strictly compliant SMTP libraries.
A patch is below, against today's mid-afternoon CVS tree (EST). The
problem was found and the patch created by Zachary Girouard
<[EMAIL PROTECTED]>.
