# Group EMail Enabler v0.2
# Jeff Johnson <[email protected]>

# Tested with OS X Server 10.6 and 10.7
# Should also work with 10.5

# This script allows you to manage email groups using Work Group Manager.
# If you create an executive group in WGM, you then have a executive@ email address
# This is automatically maintained as you adjust the members

# The script searches your LDAP groups for the word 'mail' in the comment field
# You must add mail to the comment field for any group which should have an email address.
# The email address for that group will be the shortname of that group.
# If you miss this step (add 'mail' to the comment field), this script does nothing.

# Known issues
# 1. Only supports groups in LDAP, users can be in LDAP or Local
# 2. Does not support other groups within your email group (no nested groups)
# 3. Almost no error checking, so best to run it manually a few times to check results.

# Installation Instructions
# 1. Save this file as
#       /usr/sbin/group_email.sh
# 2. Then adjust permissions
#       sudo chmod +x /usr/sbin/group_email.sh
# 3. Modifiy alias_maps in /etc/postfix/main.cf
#    You need to add this line to what you already have
#        hash:/etc/postfix/group_aliases
#     Example, you have:
#        alias_maps = hash:/etc/aliases
#     Change to:
#        alias_maps = hash:/etc/aliases, hash:/etc/postfix/group_aliases
# 4. To run automatically every 5 minutes, I prefer a simple addition to /etc/crontab
#      you may need to create /etc/crontab if it doesn't exist
#      Add the following to /etc/crontab
#     	  */5 * * * * root /usr/sbin/group_email.sh >> /dev/null 2>&1
# 
# If you followed these instructions, within 5 minutes you will see an alias file at
#  /etc/postfix/groupaliases
# you can inspect the file to confirm the results.


cd /etc/postfix

# clear current aliases
echo "" > group_aliases.tmp

# Get list of groups with 'mail' in the comment field
gr=`dscl /LDAPv3/127.0.0.1 -list /Groups Comment | grep mail | awk '{print $1}'`

# Group EMail Enabler v0.2
# Jeff Johnson <[email protected]>

# OS X Server should allow you to create a Group in Work Group Manager
# and allow you to email that group. This functionality is missing or broken
# in most versions of OS X Server

# This script allows you to manage email groups using Work Group Manager.
# If you create a 'manager' group in WGM, you then have a manager@ email address
# automatically maintained as you adjust the members

# You must add mail to the comment field for any group which should have an email address.
# The email address for that group will be the shortname of that group.
# If you miss this step (add 'mail' to the comment field), this script does nothing.

# If you use these installation instructions, the script will run every 5 minutes.
