I would like to REALLY archive some older e-mail-folders. Archive seems not to be the right word, because i work with empty inboxes, so every completed or answered e-mail is still archived in a folder (with the name of the year), but i use IMAP so all archived emails are still on the server.
Now i want to EXPORT the years 2018-2019 to my selfhosted-backup-server so that i can delete the emails on the mail-server.
a) Which format make most sense? EML? mbox? Another one? Would be nice if i can search the archived stuff without too many effort. b) Should i export directly from the UI of my mailprovider (if possible) or is exporting from thunderbird-client ok.
I think that is the way I want to go! Thunderbird on my PC is the „central mail client“, so I just have to draw the archived years (imap) to a local folder. The advantages: If I look for an older mail, I do not have to search in seperate archived files (mbox/eml). And with backing up thunderbird, I have a backup of all my settings AND mails!
