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.
That’s me! I got dovecot in docker working for email archive, and moved all my old emails there. I access them through thunderbird on pc and k-9 mail on phone. Works great!
It took a bit of time to set up the passwords, and understanding the configuration. I used the lets encrypt certs from caddy.
I had to look at some different examples of the dovecot config file to get it right
