In mail, 'From' becomes '>From'

["Karsten M. Self" <kmself@ix.netcom.com>]

I've been noticing this on a number of messages both from and to me.

Some lines beginning with 'From' are rewritten as '>From'.  Needless to
say, this utterly borks things like GPG signatures.

I have no idea where this is happening (I run exim, fetchmail and mutt),
or even if it's characteristic of my system, my ISP
(Earthlink/Mindspring), or other mail intermediaries.

Suggestions?

Peace.
