I love puzzles!
But I'm not sure what you mean by "one line", other than you typed it
on one line.
So just to make sure we are talking about the same thing...
DATA
<headers><CR><LF>
beginning of line 1<LF>more of line 1<CR><LF>
.<CR><LF>
right?
Well, the easy one first. If the message was sent as a normal RFC-822
only message, I'd expect the unix mailbox to contain...
<headers>\n
beginning of line 1\n
more of line 1\n
since RFC-822 anticipates local newline conversions.
whereas if it were a MIME message sent with 8BITMIME, I'd expect something
like...
<headers>\r\n
beginning of line 1\n
more of line 1\r\n
I guess if this is really important, we could try feeding such a message
to sendmail with 8BITMIME and see what it does.
But I'm not sure I see where this is going. Qmail would never deliver
such a message, it would barf. The case you are also stating in specifically
one of delivery, where local newline standards come into play. What about
the case of transport?
