One variant of the Unix mailbox format uses /^From / to designate the
start of messages and thus (destructively and stupidly) escapes lines
in the body matching that with >.  (Another uses Content-length
headers.)

This sort of thing is endemic to the net... you could try figuring out
which mailer is doing that and try to convince it to use a different
variant of mbox or switch to maildir (which may require switching from
exim, I dunno), but it's just as likely that it's your ISP, the
sender's system, or something like that.  

Really, people signing messags with /^From / in the body should be
qp-escaping that anyway, because there's so much software out there
which would break messages like that....
