You seem to imply that servers mess > with the body. Why would it need to? Mind explaining? They shouldn't "mess" with it, unless told to. You're right. I was referring to the way input characters are treated by the program that implements the SMTP service. If the program makes stupid assumptions about the size of character data, and uses data types in C like `char' instead of `int' then it's not just the client's fault when 8-bit data get mangled. > > Outlook is infamous for its habit of sending 8-bit characters > > unencoded in MIME messages that lack proper Content-Type: headers. > > The result is rather interesting to look upon, when the message passes > > through multiple SMTP servers, with different settings each. > > I didn't realize that the other poster was referring to MIME mail > (partially because the message I complained about didn't use MIME). > Yes, I've seen really messed up MIME mail.

It's usually the sending clients that don't properly encode messages, and assume that the receiving end will Know What To Do(TM).
