No.  RFC821 and other mail standards require that case differences in the local
or userID part of the address (left of '@') MUST be preserved, so LISTSERV must
do so as well.  Be thankful that LISTSERV now gives this warning:

Note also that in some DBMS based lists (where the UEMAIL field is configured as
a unique key) this is no longer allowed to happen, although case is still
preserved as required.
