Upload Maildir to Google Mail

I recently needed to move some clients’ mail accounts to Google’s GMail hosting. I currently use Dovecot to host mail on the particular machine being migrated and this stores the mails in a Maildir format. To migrate existing mail stored on this server to the GMail service I wrote a little script in Ruby to make it easier. It has the following features:

It defaults to uploading the mails in to the GMail ‘Inbox’ but this can be configured. This enables you to put them all into a different folder and then sort them out from there. In GMail, IMAP folders are just ‘labels’. Most other options have sensible defaults.

Use at your own risk but if you find something wrong then please tell me. You can get it from my public git repository.
