Hey folks,
Provided you’ve gotten your cPanel host migrated to Maildir, you could use the following script I crafted up to move your mail data over. Bear in mind, should this script kill your dog, burn down your house, or take a dump in your Cheerios, it’s your problem. I’ve used it to move a couple domains over and have had pretty good luck with it.
I should also mention that you’ll have to run this as root, so use extreme caution.
#!/bin/bash
#Copy cPanel mail data to InterWorx host

#Do yourself a favor and set up an ssh key with no password or an ssh-agent
if [ ! $# == 4 ]; then
echo "Usage: $0 remote-user local-user domain host"
exit
