[Mimedefang] mimedefang compalins about suspicious char, but none present

[Aleksandar Milivojevic]

I've just got an email that was rejected by MIMEDefang.  It complained 
about suspicious chars.  After examining copy of message in quarantine, 
it doesn't seem to contain anything suspicious.  Only printable ASCII 
and tabs.  Any other explanation for this?

Sorry for not including the offending message (too much data useful for 
identity theft in it).  Hope you understand.
