Kudos on the amusing node title. And your coding style did not cause me to pull a face. That said, I made some minor "improvements" based on my personal taste: 

sub logger {
    my $entry = shift;
    my $logpath = 'C:\\Logs\\MailServer\\';
    my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localti
+me;
    my $datestamp = sprintf '%04d_%02d_%02d', 1900+$year, 1+$mon, $mda
+y;
    my $timestamp = sprintf '~<%02d:%02d:%02d>~', $hour, $min, $sec;
    my $logname   = $logpath . $datestamp . '.log';
    my $logline   = $timestamp . $entry;
    if (defined $entry) {
        open my $LOG, '>>', $logname or die "open: '$logname': $!";
        say $LOG $logline or die "say: '$logname': $!";
        say $logline;
        close $LOG;
    }
}

Note the minor differences and make up your own mind. In particular, note the use of sprintf so that the dates and times are formatted more uniformly and thus sort correctly.
