How can I access the mail stored in a full linux website backup?
If I unpack the backup on my Windows machine, I see the mail folders: /homedir/mail/[site_name]/[user_name]. But ... how can I access the messages? I tried following steps for importing messages into Thunderbird, but since these folders do not contain *.eml format messages, Thunderbird doesn't find anything it is able to import.
Alternatively, I could upload the the .gz file of the site backup to a cloud server, unpack it, and do something there, in linux. But I'm not sure what to do.
