Caboth Is it possible to upload all the email on the server to an AWS bucket so it can be imported into an archive system?
esackbauer Then it depends which format the archive system can read. You could upload the whole maildir structure (check the dovecot documentation on that), but you need to decrypt it before: https://docs.mailcow.email/manual-guides/Dovecot/u_e-dovecot-mail-crypt/
