When migrating email services one does not want to lose the old messages. This tool copies messages from one IMAP system to the other

Here is a sample script to get started

#!/bin/bash -x

curl http://cdn.edoceo.com/bin/imap-move.php > imap-move.php

php ./imap-move.php \
    --source imap-ssl://userA@domain:secretA@imap.example.com:993/ \
    --target imap-ssl://userB@domain:secretB@imap.example.com:993/sub-folder

Command Options

This IMAP copy script supports a few options.

--source
A URI style pointer to the source IMAP mailbox
--target
A URI style pointer to the target IMAP mailbox
--fake
Will simply list the messages and folders that would be copyied
--wipe
Remove the messages from Source after they have been copied to Target

Examples

Here are a bunch of examples showing how to use imap-move.php

Move from Gmail to Google Apps

This copies from an Gmail style account to a Google Apps hosted domain duplicating folder structure

php ./imap-move.php \
    -s imap-ssl://userA@gmail.com:secretA@imap.gmail.com:993/ \
    -t imap-ssl://userB@domain.tld:secretB@imap.gmail.com:993/

Move from Source to Sub-Folder on Target

We can copy mail from for example old.com to our new email system, storing these old messages in a folder calld Archive This will also work with Google Mail systems as a target. 

php ./imap-move.php \
    -s imap-ssl://userA@old.com:secretA@imap.gmail.com:993/ \
    -t imap-ssl://userB@new.com:secretB@imap.gmail.com:993/Archive

Remove from Source

php ./imap-move.php \
    --wipe \
    -s imap-ssl://userA@old.com:secretA@imap.gmail.com:993/ \
    -t imap-ssl://userB@new.com:secretB@imap.gmail.com:993/Archive
