Exim's behaviour is "guess what was meant". it actually checks the line
ending of the first line in the message to determine what convention the
sender prefers. if it sends CRLF, Exim will *only* accept CRLF for the
rest of the message. the same is true for LF.

since a conforming implementation MUST NOT send an LF on its own in a
header field, I feel Exim's behaviour is sound.
