Could it be that the sending mail client is putting in the folds (and
the mail server leaves them in). Then the receiving mail client displays
them as breaks since the subject line display length would be (and usually
is) different than the subject line display length of the sending
application?

> These "funny breaks" are likely "folding". I'm not sure *why* IMail would
do that, as I can't see a reason that IMail should. But, RFC 822 allows for
something called "folding". If a header is long, you are allowed to
continue it onto the next line, by having the next line start with a space
or tab.

(not just E-mail that you had sent from a client you are willing to work
with solely), you would have to be able to handle the folding issue. It's a
royal pain, and dealing with headers would be a LOT easier without it, but
remember those RFCs were written almost 20 years ago! A 500 byte header
would take up a significant portion of the memory of PCs from those days.
