you can tell Exim to claim to support it, but it is not true. RFC 1652
says:

Once a server SMTP supporting the 8bit-MIMEtransport service
extension accepts a content body containing octets with the high-
order (8th) bit set, the server SMTP must deliver or relay the
content in such a way as to preserve all bits in each octet.

If a server SMTP does not support the 8-bit MIME transport extension
(either by not responding with code 250 to the EHLO command, or by
not including the EHLO keyword value 8BITMIME in its response), then
the client SMTP must not, under any circumstances, attempt to
transfer a content which contains characters outside the US-ASCII
octet range (hex 00-7F).

Exim has no code for converting MIME parts from 8bit to base64.
