How do you archive your e-mails? What format should the archive-files have? eml? mbox?
(heise.cloudimg.io)
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.
MBOX is a standard format, which is text based, (like the emails themselves are) and should be compatible across multiple email clients. It can contain entire folders.
EML is also a standard text format, but usually contains a single email in each file.
In the worst case, you can just open up either one in a text editor if you need to find something.
