Old legacy script I wrote for maintaining servers.

script.sh

#!/bin/bash

# In an effort to automate some of my daily tasks I decided to write this mail quota monitoring script. It gets all quota information, processes it, then Twitters the information AND sends an e-mail. The Twitter information is vague so security isn’t compromised, but the e-mail has the details.  This way I can get a heads up of impending doom on certain mail accounts!

# Get the e-mail ready.
Email="esupport@exyst.com";
Subject="Xync: Account(s) Exceeding Quota(s)."
Message="/tmp/message.txt"
# This starts the message fresh.
echo "Summary:" > $Message

# Generate data about all mail boxes.
MailBoxQuotaData=`/opt/zimbra/bin/zmprov gqu localhost`;

# Set counters.
Counter=0;
AccountCounter=0

# Sort through the data.
for Line in $MailBoxQuotaData
do
    Counter=`expr $Counter + 1`;
    case "$Counter" in
            "1" )
                    Account=$Line
            ;;

                    # If the limit is 0 then it 
                    # has no limit.
