If my memory still serves me I do not agreee. An RFC header continues until
the first blank (empty, null) line. Then comes the body.
What this means is that you do not have to check for valid headers, you
only have to check for a blank line.
Of course letting the messages pass VAX-11 mail will break everything. It
only handles From: To: and CC:. The rest of the headers you have to put in
the body of the message, if you want to keep them.

Of course I may be wrong. I have to look into the RFC,
