But Exim won't return the viral message in its original, dangerous,
MIME-encapsulated form. All the MIME headers that triggered the virus
detection are out in the open now, and -- omitting the possibility of
MUAs that deliberately go looking for trouble by interpreting non-MIME
messages as MIME [1] -- the recipient should be safe.
