basic server check script - help

Hello Fellow bash enthusiasts...

I am stuck on this local script and could use some fresh eyes on this code.

Code:

#!/bin/bash
MAIL_ME="jj@uberdork.com"
MAIL_SUBJECT="Norveld_Server_needs_attention"
SERVER_DATE=$(TZ=PST8PDT date)
echo $(ServerTZ=PST8PDT date) - Web Server Check = $(curl -Is http://xxx.xxx.xxx.xxx | \grep -E '^Server' | cut -c9-) >> /home/jj/Documents/cirrhus9/Accounts/Norveld/3WeekTest/norveld.test
if [ $? -eq 0 ] ; then
 exit 0
 else
 if [ $? -eq 1 ] ; then
 echo "Norveld_Server_Check - FAILED" on $SERVER_DATE | mail $MAIL_ME -s $MAIL_SUBJECT
 exit 1
 fi
 fi
done
#EOF

PING IS NOT AN OPTION'
Server when it's borked will ping,
but be unresponsive, so I ask the Webserver what software it's using with

Code:

curl -Is http://xxx.xxx.xxx.xxx | \grep -E '^Server' | cut -c9-

which returns "Microsoft-IIS/7.5" and works even if the server is unresponsive through usual means.

This runs under my cron every minute.
There's only 1 problem, server has been up/down for awhile and I NEVER get an email.

Code:

telnet xxx.xxx.xxx.xxxx 80

is an option, but I have zero experience with how to handle the response from the server. or

Code:

wget xxx.xxx.xxx.xxx/index.html

Whatever method I use to check for responsiveness, I have to get an email as the desired email address.

local: GNU bash, version 4.1.10(1)-release (i586-suse-linux-gnu)
Remote: Windows Server 2008 R2 (64bit) with IIS.

Thanks.

Happy New Year!

INSTALLSIEVE(1) 					      General Commands Manual						   INSTALLSIEVE(1)

NAME

       installsieve - user utility for managing sieve scripts

SYNOPSIS

       installsieve

DESCRIPTION

       installsieve is a utility that allows users to manage their sieve scripts kept on the server.

OPTIONS

       -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.

       -l  List  all  of  the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
       script.

       -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.

       -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten.  Upon  sucessfully
       putting	the  script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
       sieve names may not contain a '.'.

       -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..

       -d <name> Delete the sieve script on the server with <name>.

       -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.

       -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already  exists  it	is
       overwritten.

       -u <user> Userid/Authname to use for authentication; by default, the current user.
