Migrate e-mail addresses/forwards from CPanel to iRedMail

export.sh outputs a list of all e-mail addresses and forwarders on a CPanel server in a format which import.sh can import into iRedMail (SQL).

maildirs.sh is a helper script to be run on the source server which will output all e-mail addresses followed by their maildir path. This can be used for copying mailbox contents over to the new server.

copy_maildirs.sh can use the output of maildirs.sh (see config.sh) to copy maildir contents from the source server to the target server. This script is to be executed on the target server and requires rsync to be installed on both servers, and assumes the target server can SSH into the source server withotu the need for a password (if not: ssh-copy-id).

Usage

1. On the source server, run bash export.sh > exported.
2. Copy exported into the same folder as the import.sh script (and config.sh) on the target iRedMail (SQL) server.
3. Set the correct parameters in config.sh on the target server.
4. Run import.sh on the target server.

Note

These scripts have been written for a very specific setup, and are unlikely to work for any other setups. The only scenario where this script will work is if you wish to migrate all your e-mail addresses from a CPanel server to an iRedMail server with MariaDB/MySQL. I haven't looked into where/how CPanel stores catch-all e-mail addresses, but the scripts haven't been tested with those, either.
