I think Jim Pachowski's comment earlier in the thread is the most likely
explanation: the = characters are from quoted-printable encoding.  This
uses the = as an escape to encode 8-bit data using printable ASCII
characters, and also makes all the lines no more than 76 characters long
(before encoding), as in the example in Victoria Stuart's message.  (See
RFC 2045, which replaced RFC 1521 on this.)  

Can you look at the actual message source for one of these messages and see
if there's a header saying "Content-Transfer-Encoding: quoted-printable"?
