Email Line Formatting

[afrinspray]

I couldn't find a general email questions newsgroup, so I apologize if
this is a little off-topic.

I'm building a list-server program, and I'm parsing the email bodies
from incoming messages. I'm having problems determining if lines are
wrapped automatically or if the user pressed enter. I read some RFCs
on the matter, and they say that lines can be folded in the headers. I
couldn't find anything about the body of messages, so I was wondering
if anyone knew an easy way to determine if the line has been folded vs.
hard returned by the sender?

Even if it's just a "please post in [this] newsgroup, you jerk", I
appreciate your comments in advance.

If the message is plain text, there's no way to determine that. If the
message is encoded in MIME's Quoted-Printable format, it's obvious.
