In case you don't know....
mbox files store emails with "From " on a new line recognised as the beginning of a new email (and thus the end of the last).
There are various formats, but a typical first line will be something like
From - Fri, 20 Oct 2000 11:34:32
(sometimes the sender name is included here, sometimes the date format differs, probably due to history of client used, sometimes there's no dash; the actual information is still available in various other headers)
The problem is.....
When moving emails from one folder within Local Folders (I haven't tested imap folders, but that's not what I need), the information is stripped, leaving only "From " (followed by new line). The remainder of the email is fine, and moving folders whole retains all information.
I've tried drag and drop, and I've tried "Copy..." dialogues. I've tried message filters. I've also tried a couple of extensions (I presume they just use the built-in file moving code). All exhibit this behaviour.
(for info, I'm trying to rebuild my archive in a logical way from zillions of backups, and for whatever reason this behaviour spoils the ability to remove duplicates via the "Remove Duplicate Messages" add-on, which does cope otherwise - I'm trying to merge multiple folders from maybe 25 years(!). I haven't even started on my Outlook .pst archives!)
(Bonus - another one, which may be intentional - when moving emails from one folder to another, the source mbox file keeps all the moved emails, and only its .msf index is updated. Go to "Properties... Repair Folder"; the .msf is recalculated and all your moved emails reappear magically.)
Basically things work under the hood, but it's all a bit flaky.... ;-)
Anyway, thanks, and do as you will with all of this! :-)
