That's two translations, and two chances of corrupting the emails. Even for mbox format there are four main variations with minor deviations. It would seem safer to not need to alter the file contents at all. http://kb.mozillazine.org/Importing_and_exporting_your_mail#Mbox_files If Thunderbird is already happy with the contents of its own mbox files then give them back to it. I did see `the application automatically discovers new mbox files and makes them into folders' on that page I suggested to Tim. He could avoid the Import→Tools, perhaps. http://kb.mozillazine.org/Importing_and_exporting_your_mail#Manually_importing_and_exporting Cheers, Ralph. -- Next meeting: Bournemouth, Tuesday, 2018-09-04 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:firstname.lastname@example.org / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR
