As others already wrote, the normal behavior is to treat the address
case-insensitive. Local parts can be made case-sensitive in
searches/lists/routers, and with Regex you can even do case-sensitive
stuff with domains. But thats not the default!
Check your configuration if you have anything like +caseful as a address
list element somewhere or caseful_local_part on a router. In the absence
of these, exim does a lower-case of the local part and compare caseless,
the domain itself should always be handled in lower-case internally.
What is more important is, if you have any lists you do lookup against,
the key values must be lower case, because exim does convert the string
to look for to lower case before processing the lookup, if you don't
include one of the two options above, overriding this behavior.
