On importing mbox files, originally from a mailing list, I see that about 3500, out of 66000, are being incorrectly assigned to a user.
Here is the first, and two other, lines from the header:
From csgnet@lists.illinois.edu Fri Dec 12 12:55:30 2014
From: “Dag Smith” (user@pctresources.com via csgnet Mailing List) csgnet@lists.illinois.edu
X-Original-From: Dag Smith user@pctresources.com
Is the import script only using the first line, as that is the email that is being used for the user rather than the correct one, user@pctresources.com?
It should really be using “X-Original-From”, do we have any control over that?
