Ah, that's just your email client and mine (Apple Mail in that case, Outlook
right now...) disagreeing about what the default encoding for the text is.
Something in the path between you and I thinks that the equals symbol "=" is a
reserved character and is attempting to escape it...
It's a fairly common problem, particularly if one (but not both) of the
participants is using Outlook, so you'll probably get to see it a lot!
Anyway, if it's just a single file that is involved, it should be trivial, no
headers need be involved at all!
Here's a little example fragment; try this, see if it works for you. It may
show what I think you need to be doing.
Though, since I am posting from Outlook, there is a very real chance all the
"=" signs will be messed up again!
If so a global search and replace to convert "=3D" into "=" might work...
