I’m new both to archiving mail and EagleFiler. The process of importing mailboxes wholesale from Thunderbird to EF has been painless.
But behavior in Thunderbrid was set to the default, automatic download of images was set to off, i.e. not to download images. So now I want to back up numerous mail boxes with thousands of incomplete emails. After a couple of days of experimentation and research it seems that neither Thunderbird or Apple Mail will retroactively download all images (or attachments).
The only way forward I can think of is to individually select each of the many thousands of emails to load the images, before then moving/importing to EF. I can’t imagine I’m the first, so any suggestion of this or another mail app that would accomplish this would be wonderful.
