[MM3-users] Hyperkitty_import.py Error

I am trying to import some old archives (going back to 2003) into a Mailman 3 list. The import job is terminating very early in the process with the following error:

IndexError: string index out of range

1. Is there a way to fix a mbox file that is generating this type of error?

2. If a message is causing this error, is there a way to import the rest of the mbox file by importing messages after a certain date within the mbox file? I know the --since flag should be able to do that but I am unsure what the date/time format should be.

3. The --no-sync--mailman flag indicates the possibility of doing batch imports. What are batch imports and how do you do them?

Thanks!
