Uploading a local mail box file “Friends.mbox” to the remote mail box “imported” on the server “example.com” using SSL:

python imap_upload.py Friends.mbox imaps://example.com/imported

You can specify the destination by options instead of URL:

python imap_upload.py --host example.com --port 993 --ssl --box imported Friends.mbox

You can use a shortcut option for the Gmail server:

python imap_upload.py --gmail --box imported Friends.mbox

There's an --error option so that you can store the failed messages in mbox format and retry for them later:

python imap_upload.py --gmail --box imported --error Friends.err Friends.mbox

You can also recursively import mbox sub-folders using th -r option:

python imap_upload.py --gmail -r path
