Your regex will match the actual `From` header of emails. Are you sure that your separator between emails contains a colon? Usually it looks like `From foo@example.com Sat Aug 18 19:23:56 2018`. Note that there is no colon after the “From”, because that should be reserved for the email header. If there is a colon in your separator, you might need to find another way to cleanly separate the emails in the mbox file. You are importing from mbox, right? Not just a bunch of emails where every email is stored in its own file? --- _[View the full topic](https://meta.discourse.org/t/imported-mbox-file-mails-all-have-user-system/106567)._
