trying to understand 8bit emails
I'm trying to understand 8bit emails. Using mutt I send an email with a jpeg
attached, for the jpeg I specify 8bit encoding. I send the email off and
although it's viewable on the other end and appears to be intact (i.e. I can
view it) doing a diff between the emailed jpeg and the original shows that
there are differences.
All servers along the way are postfix. I've tried sending 8bit email with
kmail as well and with kmail the files are different as well, so different
that the emailed copy doesn't resemble the original in any way when viewed.
I always use base64 encoding personally (well occasionally uuencoding) I am
asking this because a customer of mine seems convinced of the need for 8bit
encoding. According to what I see in postfix docs and
http://www.faqs.org/rfcs/rfc1652.html things should work.
Does anyone have some pointers on where things might be going wrong? Is there
an 8bit email FAQ somewhere (doesn't have to be postfix specific). Here the
smtp session captured with sniffing session on the remote server:

8bit garbage starts here ...
