# ForwardMails 1.0, July 2007, Andre Aulich, www.andre-aulich.de
#
# We need a file with a definition of our forwardings.
# It should look like this:
#
# test1:  first1.last1@keriomail.domain.de
# test2:  first2.last2@keriomail.domain.de
# test3:  first3.last3@keriomail.domain.de
# test4:  first4.last4@keriomail.domain.de
# test5:  first5.last5@keriomail.domain.de
#
# Make sure there's only one colon per line.
#
# Define the path to the Forwarders file:

FORWARDERSFILE=Forwarders.txt

# First, let's generate a list of users:

for i in $(cat "$FORWARDERSFILE" | awk -F":" '{print $1}')

# For each user we need his alias shortname in the form of
# 'firstname.lastename'. Let's take this from our list:

do
	MyForwarder="$(cat "$FORWARDERSFILE" | grep "$i" | awk -F" " '{print $2}')"

# Output what we are doing:
	echo "Mails for $i will be forwarded to $MyForwarder."

# Now, actually do it:
dscl -u diradmin -P DIRADMINSPASSWORD /LDAPv3/127.0.0.1/ -create /Users/$i apple-user-mailattribute "<?xml version="1.0" encoding="UTF-8"?>
<dict>
        <key>kAPOPRequired</key>
        <string>APOPNotRequired</string>
        <key>kAltMailStoreLoc</key>
        <string></string>
        <key>kAttributeVersion</key>
        <string>Apple Mail 1.0</string>
        <key>kAutoForwardValue</key>
        <string>$MyForwarder</string>
        <key>kIMAPLoginState</key>
        <string>IMAPAllowed</string>
        <key>kMailAccountLocation</key>
        <string>fully.qualified.domain.name.of.your.server</string>
        <key>kMailAccountState</key>
        <string>Forward</string>
        <key>kPOP3LoginState</key>
        <string>POP3Allowed</string>
        <key>kUserDiskQuota</key>
        <string>0</string>
</dict>"

# MAKE SURE, THAT IN THE XML PART ABOVE YOU ADAPT THE kMailAccountLocation
# PART TO YOUR ENVIRONMENT!
