Here are the scripts I use. DON'T use these as-is, just read code to
understand the procedure.
This script gets run on as root on the box from which the list is being
if [ "$1" = "" ]; then
echo 'Usage: tar_list.sh <listname>'
if [ ! -e /var/lib/mailman/lists/$1 ]; then
echo "$1: No such list!"
echo Creating $1_list.tar.gz ....
tar -czvf $1_list.tar.gz $1
mv $1_list.tar.gz /tmp/$1
echo Creating $1_archive.tar.gz ....
tar -czvf $1_archive.tar.gz $1
mv $1_archive.tar.gz /tmp/$1
echo Creating $1_archive_mbox.tar.gz ....
tar -czvf $1_archive_mbox.tar.gz $1.mbox
mv $1_archive_mbox.tar.gz /tmp/$1
if [ -L /var/lib/mailman/archives/public/$1 ]; then
This script gets run as user mailman on the receiving box:
if [ "$1" = "" ]; then
echo 'Usage: untar_list.sh <listname>'
echo "Give root password on remote system ..."
scp root at shanti-vpn.fmp.com:/tmp/$1/* .
echo "Creating list $1 ..."
tar -xzvpf ~/tmp/$1_list.tar.gz
echo "Creating archive for $1 ..."
tar -xzvpf ~/tmp/$1_archive.tar.gz
echo "Creating archive mbox for $1 ..."
tar -xzvpf ~/tmp/$1_archive_mbox.tar.gz
if [ -e ~/tmp/$1_archive_is_public ]; then
ln -s /var/lib/mailman/archives/private/$1 /var/lib/mailman/archives/public/$1
echo "If no errors, delete files in ~/tmp and delete /tmp/$1 directory on remote system"
If you're using an older version of mailman on either system which puts
things under /usr/local/mailman then you'll need to make allowances for
this in the paths. Note that the tarball containing the list to be
moved contains a zero-length file, <listname>_archive_is_public which is
just a flag file to direct the script on the receiving side to create
the appropriate symlink for public archives.
These scripts work fine for me, and I've used them successfully, with
minor variations, on two different major moves.
