Upgrade from what to what?

The newline is a result of RFC 2822 header folding applied to long
headers. The headers may start out long or they may grow because of
the addition of the subject prefix. MUAs such as Outlook Express and
Mozilla should unfold the subject and display it without the newline.

I don't know what would cause this. Does it happen for all posts or
only on posts from the ticket system? i.e. what happens if you send a
normal email post to a ticket list?

What does the actual, raw subject look like if you view the 'message
source'?
