This should actually never happen - as long as the boundaries etc. are on
seperate lines they should work just fine. Do you have any samples of such
messages? What mail clients are you using?

From the Changelog for revision 1.35:

    Modified multipart-MIME and Base64 code to properly preserve multipart
    pre- and postambles and whitespace near MIME boundaries.
