Hi Eric,

I had some fun with pdf files too (even before I met SA the first time),
but I receive binary files pretty often ... and usually undisturbed

A pdf file MAY look like a text file to a naive sender (this depends on pdf 
features,
and the pdf spec specifically has a few non-text characters within the first 
512 bytes,
meant to convince a mail sender guessing text/binary rather than knowing file 
types)
IF it happens to be treated as text, chances are that at some point in the mail 
flow a line
ending conversion is applied to the pdf file .... and this will certainly break 
it.
It is certainly not the SA to blame here but whoever believes that sending 
enough non RFC
compliant mails around will make the world change to non RFC behaviour.
AFAIK RFC821 says that mail is NOT 8 bit transparent
