Exim always lower cases domains for routing (because they are defined to
be case-insensitive). By default, Exim lower cases local parts as well,
because that is what is normally wanted. However, you can set
caseful_local_part on any router if you want it to treat local parts in
a case-sensitive manner. There are various comments about this in the
book and the manual.
However, when Exim does an SMTP delivery, as in the above log line, what
is actually sent in the RCPT command is the address with the original
casing preserved. That is, what the log line is telling you is
(a) The routing was done using "mamoune@???".
(b) The mail was transmitted using RCPT TO:<MAMOUNE@???>
