You should only add your local network if you have an application that needs to submit messages but cannot authenticate. When this is the case, it's best to use a single IP address, not such a big range. This is a security risk. 2) The way you've specified it, the 2nd line will be true so your 3rd line will never take effect. The :allow... line should always be last. I would go back to the stock settings in this file, then redo cdb again. -- -Eric 'shubes' - Qmailtoaster is sponsored by Vickers Consulting Group (www.vickersconsulting.com) Vickers Consulting Group offers Qmailtoaster support and installations.

[qmailtoaster] Re: Bulk user import script
Halo John,
I am replied to qmailtoaster list so everyone can also use it as
reference for future use or correct me If I am making an error.
In your case, I have modified the script into below

#
# Created after I ran into an issue of creating 20,000 users on my toaster!
# Initial ideas come from a script that PakOgah "pako...@pala.bo-tak.info"
# helped me with.
# Still very manual, but Work in Progress
#
# Suggestions to akisa...@ucu.ac.ug
#
# Change a few variables and you are good to go
#
#
# Location of the users file
# Rememeber that the users file is in the format
# Firstname Lastname Username Password
USERS_FILE="/path/to/file.txt"
# The mail domain to which users are created
#
MAILDOMAIN="@domain.com"
# the vadduser command
QMAILADD="/home/vpopmail/bin/vadduser"
# Select a default password for all users
#PASS="mypass"
#Specify the Default Quota_in_bytes for your Users
# 10 MB = 10 x 1024 x 1024
QUOTA="10485760"
#Fun starts here No more variables to change below this line
cat ${USERS_FILE} | \
while read FIRSTNAME LASTNAME USERNAME PASSWORD
do
echo "adding the user: $USERNAME"
$QMAILADD -q $QUOTA -c "$FIRSTNAME $LASTNAME"
$USERNAME$MAILDOMAIN $PASSWORD
done

Hi,
I'm looking at using this script for a bulk user import, but the users have
passwords all ready, so I don't want to use the same default password for
everyone. What changes would I need in the script so I can use it with a
separate password for each user?
I was thinking the format for the users file could just include the extra line
for the password.
Firstname Lastname Username Password
