Yes, Exim is supposed to be entirely 8-bit transparent, but...

When data is transported over SMTP it is conceived as "lines" terminated
by CR LF, with the whole message terminated by a line containing just
".". When Exim receives data over SMTP, it
(a) converts CR LF into LF to convert lines into the normal Unix form
(b) removes the first "." of any data line, since that is how lines
starting with dot are transmitted
When it sends data it does the opposite, so binary files should get
transmitted transparently. Also, it should be OK with lines of any
length, but I doubt whether anyone has tested out the humungous cases.
I suggest you set up some appropriate tests to make sure that Exim
actually behaves as I have described.
