My work upgraded our phones to the Droids! Unfortunately the Droid could not play our company voicemails from our PBX. So I wrote this script to intercept the voicemail emails, convert the wav file to an mp3 and then forward the voicemail to the original user.

#!/bin/bash

export EMAIL='PBX <pbx>'

cd /mail/drop/new

for i in $( ls ); do

  cd mail/drop/new

  # This removes system generated emails
  axBad=$( cat $i | grep X-Original-To: | sed 's/...............\(.*\)/\1/'  )
  
  
  if [ "$axBad" == "root" ]; then
     rm -f /zxa/mail/drop/new/$i
  else
    
    # Grab the to and from address
    axto=$( cat $i | grep "To: \"\"" $i | sed 's/........\(.*\)/\1/' | sed 's/\(.*\)................./\1/')
    axfrom=$( cat $i | grep From: | sed 's/.............\(.*\)/\1/' | sed 's/\(.*\)./\1/' )
    axsubject=$( cat $i | grep Subject: | sed 's/.........\(.*\)/\1/'  )
    axbody1=$( sed -n '30,30p'  $i )
    axbody2=$( sed -n '31,31p'  $i )
    axbody3=$( sed -n '32,32p'  $i )
    axbody4=$( sed -n '33,33p'  $i )
    axbody5=$( sed -n '34,34p'  $i )
    axbody6=$( sed -n '35,35p'  $i )
    
    echo $axbody1 > /etc/postfix/vmail/proc/body.txt
    echo $axbody2 >> /etc/postfix/vmail/proc/body.txt
    echo $axbody3 >> /etc/postfix/vmail/proc/body.txt
    echo $axbody4 >> /etc/postfix/vmail/proc/body.txt
    echo $axbody5 >> /etc/postfix/vmail/proc/body.txt
    echo $axbody6 >> /etc/postfix/vmail/proc/body.txt
    
    #Strip the wav file from the eml file
    uudeview -i -p /etc/postfix/vmail/proc +e .wav /mail/drop/new/$i > /dev/null 2>&1 

    # Convert the wav file to mp3
    /usr/local/bin/ffmpeg -i /etc/postfix/vmail/proc/msg0001.WAV -ab 8k /etc/postfix/vmail/proc/msg0001.mp3 > /dev/null 2>&1 

    #send the new email out
    cd /etc/postfix/vmail/proc
    mutt -n -s "$axsubject" -a msg0001.mp3   -- "$axto@mydoamin.com"  < body.txt

#clean up directory
rm -rf /etc/postfix/vmail/proc/*.*
rm -f /mail/drop/new/$i
fi
