the vacation feature stumbles over invalid headers in several cases, causing an even more invalid header

f.ex. if the original mail contains a line with only spaces in the vacation reply the header breaks apart displying not only the inteded vacation message but also parts of the message header. depends a bit on the client what happends of course, thunderbird and the mac client are two examples.
