A small Ruby script to transfer email between two IMAP accounts, great for transferring Gmail accounts.

imapsync_ruby

This is a small program that will help copy messages from one IMAP folder to another, even across servers. It makes it really easy for example to migrate from one gmail account to another, and it has also been tested with many different IMAP servers.

USE AT YOUR OWN RISK.

Instructions

1. Open up the imapsync.rb file and edit lines 6 - 19 as needed.
2. You will need to provide a host name, user name, and password for the source account and the destination account.
3. You can optionally change the UID_BLOCK_SIZE if necessary.
4. To automatically discover IMAP folders to sync, use the --dynamic_folder_map option when executing the script.
