Exim is 8-bit clean.
In Exim 4, you can force a rejection after DATA by an ACL entry such
as
deny condition = ${if match{$message_headers}{[\x80-\xff]}{yes}{no}}
(possibly elaborating the regex to include low-valued non-ASCIIs as
well).
But how much good is this in practice? We know that some MTAs just keep
trying again after rejections following DATA. And you'll probably start
blocking messages from people with accented characters in their names,
or who put an accented character in a Subject line. So it just causes
the users more hassle.
