It looks to me like the problem is really a bug in mm-handler.
Normally, there is not an issue when aliases are used to invoke the
wrapper.

The problem appears to be that mm-handler just assumes the recipient
address of the incoming mail is lower case. I.e. the 'validfields'
which are used to validate the command portion of the
listname-command at ... address are all lower case and the listname
portion is used in a test to see if the $prefix/listname/config.pck
file exists.

I'm not fluent in perl, but it seems that

        $list = $addr;

in the following piece of mm-handler
 

ADDR:   for $addr (@to) {
        $prev = undef;
        $list = $addr;

should be

        $list = lc $addr;
