Email Admins - I have a Question


OK - so we are running Postfix with ClamAV, Spamassassin, & Dovcot. This really has nothing to do with the question but it may be helpful. My question is very simple. When I add a user to out mail server, we have a temp. .txt file called "user-list.txt".

When I add a user to our mail server, I become root and I "vi" that .txt file. In that file I need to enter the users info exactly

jdoe:John:Doe:1234

The above example shows his username:First name:Last Name: Last 4 of SS#. I then save the .txt file and then we have a script under /usr/local/sbin called "create_user.sh". I run this script and it will auto generate a mail account on the server for the entries I have in the "user-list.txt".

Does anyone else find this a strange way to add / manage users to your mail server?

Also - How can I ID a user on the email server? Is there a way I can find if I am deleing Bob Smith or Bryan Smith's email account? All I can see is their home dir is "bsmith" and this tells me nothing so I am scared to delete someones info. In Exchange, I can get properties of the mailbox and see who it really belongs to.

Any advice? I will post how the script looks below in case anyone can add or make any suggestions.

Code:
#!/bin/bash

# This is a script to be used to create an mail account.
#    It takes information interactively, and creates a user,
#    sets permissions on the home directory, and adds them to
#    the proper mailing lists.

IDE_USERLIST_FILE=/tmp/userlist.txt
IDE_USERLIST=$(sort --field-separator=: ${IDE_USERLIST_FILE} | awk -F":" '{print $1}')
PREVIOUSDIR=$(pwd)
MAILMANDIR=/var/mailman

echo "----------------------------"

for u in $IDE_USERLIST; do
        IDE_USERNAME=$u
        IDE_FIRSTNAME=$(grep "^$IDE_USERNAME:" $IDE_USERLIST_FILE | awk -F":" '{print $2}')
        IDE_LASTNAME=$(grep "^$IDE_USERNAME:" $IDE_USERLIST_FILE | awk -F":" '{print $3}')
        IDE_LASTNAME_LC=$(echo $IDE_LASTNAME | tr '[:upper:]' '[:lower:]')
        IDE_FULLNAME="$IDE_FIRSTNAME $IDE_LASTNAME"
        IDE_SSN_DIGITS=$(grep "^$IDE_USERNAME:" $IDE_USERLIST_FILE | awk -F":" '{print $4}')
        IDE_USER_EXISTS=$(grep -c "^$IDE_USERNAME:" /etc/passwd)
        IDE_PASSWORD=$(echo $IDE_LASTNAME_LC$IDE_SSN_DIGIT  S)
        #echo -e "USERNAME:\t$IDE_USERNAME"
        #echo -e "FULL NAME:\t$IDE_FULLNAME"
        #echo -e "PASSWORD:\t$IDE_PASSWORD"
        if [ $IDE_USER_EXISTS -eq 0 ]; then
                useradd -g users -d /home/$IDE_USERNAME -s /bin/false -c "$IDE_FULLNAME" $IDE_USERNAME && echo "User account created."
                cd $MAILMANDIR/bin
                echo "$IDE_USERNAME@domain.org" | ./add_members -r - everyone
                cd $PREVIOUSDIR
                echo "$IDE_PASSWORD" | passwd $IDE_USERNAME --stdin
                echo -e "USERNAME:\t$IDE_USERNAME"
                echo -e "FULL NAME:\t$IDE_FULLNAME"
                echo -e "PASSWORD:\t$IDE_PASSWORD"
        else
                echo "*** INFO:  USER $IDE_USERNAME already exists!  Will NOT create."
        fi
        echo "----------------------------"
done

re: Email Admins - I have a Question

I have seen a lot of scripts used to create accounts. When you are dealing with hundreds or even thousands of email addresses created in bulk, a script is the only sane way of doing it. Redhat/Fedora even has a script with the distro called newusers. The script you posted isn't necessarily what I would build, but if it does the job...

As far as determining the full name of the user, try typing: finger bsmith <enter> from the command line and it should return the info you are looking for.

Also for the full name info, in addition to the finger command, that info should be stored in /etc/passwd . Or it is on my system anyways.
