I think RFC822 says: 1) Quoted strings (qtext) may be folded. See Appendix D 2) There is no syntactic difference between a single linear-white-space character and multiple contiguous linear-white-space characters in structured field bodies. See Section 3.4.2 If so, the MUAs having trouble with folded boundary strings are broken. Glenn
