True -- so that is not strictly a requirement ;)

Anything goes -- the target filename could also be generated ...
like this:

    my $counter = 0;
    foreach(...) {
        chomp;
        my $target = sprintf("$maildir/cur/%08d", $counter++);
        symlink($_, $target);
    }    

i.e. target filename is just counter value.
